A '''fuel cell vehicle''' ('''FCV''') or '''fuel cell electric vehicle''' ('''FCEV''') is an [[electric vehicle]] that uses a [[fuel cell]], sometimes in combination with a small [[electric battery|battery]] or [[supercapacitor]], to power its onboard [[electric motor]]. Fuel cells in vehicles generate electricity generally using [[oxygen]] from the air and [[compressed hydrogen]].  Most fuel cell vehicles are classified as [[zero-emissions vehicle]]s. As compared with internal combustion vehicles, [[hydrogen vehicle]]s centralize pollutants at the site of the [[hydrogen production]], where hydrogen is typically derived from reformed [[natural gas]].<ref>{{Cite web |title=Hydrogen Production: Natural Gas Reforming |url=https://www.energy.gov/eere/fuelcells/hydrogen-production-natural-gas-reforming|website=[[Office of Energy Efficiency and Renewable Energy]]|access-date=July 15, 2022}}</ref> Transporting and storing hydrogen may also create pollutants.<ref>[http://www.ucsusa.org/clean-vehicles/electric-vehicles/how-do-hydrogen-fuel-cells-work#.V5WDwDVu1PY "How Do Hydrogen Fuel Cell Vehicles Work?"].

==Description and purpose of fuel cells in vehicles==
{{further|Fuel cell}}
All fuel cells are made up of three parts: an electrolyte, an anode and a cathode.<ref>[http://www1.eere.energy.gov/hydrogenandfuelcells/fuelcells/basics.html "Basics"], U.S. Department of Energy, Retrieved on: 2008-11-03.</ref>  In principle, a hydrogen fuel cell functions like a battery, producing electricity, which can run an electric motor.  Instead of requiring recharging, however, the fuel cell can be refilled with hydrogen.<ref>[http://www.fuelcells.org/basics/how.html "What Is a Fuel Cell?"] {{webarchive|url=https://web.archive.org/web/20081106102819/http://www.fuelcells.org/basics/how.html |date=2008-11-06 }}, The Online Fuel Cell Information Resource, Retrieved on: 2008-11-03.</ref>  Different types of fuel cells include [[PEMFC|polymer electrolyte membrane]] (PEM) Fuel Cells, [[DMFC|direct methanol fuel cells]], [[phosphoric acid fuel cell]]s, [[molten carbonate fuel cell]]s, [[SOFC|solid oxide fuel cells]], [[RMFC|reformed methanol fuel cell]] and Regenerative Fuel Cells.<ref>[http://www1.eere.energy.gov/hydrogenandfuelcells/fuelcells/fc_types.html "Types of Fuel Cells"] {{webarchive|url=https://web.archive.org/web/20100609041046/http://www1.eere.energy.gov/hydrogenandfuelcells/fuelcells/fc_types.html |date=2010-06-09 }}, U.S. Department of Energy, Retrieved on: 2008-11-03.</ref>

The concept of the fuel cell was first demonstrated by [[Humphry Davy]] in 1801, but the invention of the first working fuel cell is credited to [[William Robert Grove|William Grove]], a chemist, lawyer, and physicist.  Grove's experiments with what he called a "gas voltaic battery" proved in 1842 that an electric current could be produced by an electrochemical reaction between hydrogen and oxygen over a platinum catalyst.<ref>{{cite web |url=http://www.fuelcelltoday.com/history |title = Fuel Cell History - Fuel Cell Today}}</ref> English engineer [[Francis Thomas Bacon]] expanded on Grove's work, creating and demonstrating various [[alkaline fuel cell]]s from 1939 to 1959.<ref>{{cite web |title=History of Hydrogen Cars and Technology, from 1802 to present! |url=https://www.greencarfuture.com/hydrogen/2018/10/30/history-of-hydrogen-cars.html#historical-times-1802-to-1999 |website=Green Car Future |access-date=November 10, 2018}}</ref>

General Electric and others continued working on PEM fuel cells in the 1970s.<ref name="americanhistory1"/> Fuel cell stacks were still limited principally to space applications in the 1980s, including the [[Space Shuttle]].<ref name="americanhistory1"/> However, the closure of the Apollo Program sent many industry experts to private companies. By the 1990s, automobile manufacturers were interested in fuel cell applications, and demonstration vehicles were readied. In 2001, the first 700 Bar (10000 PSI) hydrogen tanks were demonstrated, reducing the size of the fuel tanks that could be used in vehicles and extending the range.<ref>[https://web.archive.org/web/20120301170908/http://www.h2.re.kr/lib/download.asp?path=tech_pds%5C&filename=2%BC%F6%BC%D2%C0%CC%C1%DF%C8%F1.pdf “Hydrogen Storage Technology for the Hydrogen Economy”] . “Iljin Composite”, KCR, Korea, accessed August 2, 2011</ref>

=== Fuel cells powered by an ethanol reformer ===
In June 2016, [[Nissan]] announced plans to develop fuel cell vehicles powered by [[ethanol fuel|ethanol]] rather than [[hydrogen]]. Nissan claims this technical approach would be cheaper, and that it would be easier to deploy the fueling infrastructure than a hydrogen infrastructure.<ref name=NissanEthanol>{{cite news| url=http://www.greencarreports.com/news/1104467_nissan-takes-a-different-approach-to-fuel-cells-ethanol | title=Nissan takes a different approach to fuel cells: ethanol | first=John | last=Voelcker | work=Green Car Reports| date=2016-06-14| access-date=2016-06-16}}</ref> The vehicle would include a tank holding a blend of water and ethanol, which is fed into an onboard reformer that splits it into hydrogen and carbon dioxide. The hydrogen is then fed into a [[solid oxide fuel cell]]. According to Nissan, the liquid fuel could be an ethanol-water blend at a 55:45 ratio.<ref name=NissanEthanol/>

=== Forklifts ===
{{See also|Fuel cell forklift}}
A [[fuel cell forklift]] (also called a fuel cell lift truck or a fuel cell forklift) is a fuel cell-powered industrial [[forklift truck]] used to lift and transport materials. Most fuel cells used in forklifts are powered by [[PEMFC|PEM]] fuel cells.<ref>{{Cite web|url=https://www.forbes.com/sites/tomkonrad/2013/12/11/twelve-hydrogen-and-fuel-cell-stocks/|title=12 Hydrogen And Fuel Cell Stocks|first=Tom|last=Konrad|website=Forbes}}</ref>

PEM fuel-cell-powered forklifts provide significant benefits over petroleum powered forklifts as they produce no local emissions. Fuel-cell forklifts can work for a full 8-hour shift on a single tank of hydrogen, can be refueled in 3 minutes and have a lifetime of 8–10 years.

For transport applications such as long-haul trucks, fuel cells are a potential solution for zero emission transport. A 2022 study in ''Energies'' magazine cites relatively fast refueling times compared with electric truck charging times and the current limitations of the energy density of batteries, but they note that "operating constraints" include the "high amount of CO2 emissions [caused by] hydrogen production", the lack of storage and refueling infrastructure, H2 leakage and safety challenges, efficiency "losses in compression, storage and dispensing", .<ref>Pardi, Shantanu, et. al.

== Environmental impact ==
The environmental impact of fuel cell vehicles depends on the primary energy with which the hydrogen was produced. Fuel cell vehicles are only [[Clean technology|environmentally benign]] when the hydrogen was produced with [[renewable energy]].<ref name="Notter" /> If this is the case fuel cell cars may be cleaner and more efficient than fossil fuel cars. However, they are not as efficient as [[battery electric vehicle]]s which consume much less energy.<ref>MZ Jacobson and Co., ''100% clean and renewable wind, water, and sunlight (WWS) all-sector energy roadmaps for the 50 United States''.

==Criticism of fuel cell cars==
In 2008, professor Jeremy P.

The most efficient way to convert energy to mobility is electricity." He elaborated: "Hydrogen mobility only makes sense if you use green energy", but ... you need to convert it first into hydrogen "with low efficiencies" where "you lose about 40 percent of the initial energy". You then must compress the hydrogen and store it under high pressure in tanks, which uses more energy. "And then you have to convert the hydrogen back to electricity in a fuel cell with another efficiency loss". Krebs continued: "in the end, from your original 100 percent of electric energy, you end up with 30 to 40 percent."<ref>Blanco, Sebastian.

In 2014, electric automotive and energy futurist Julian Cox wrote that producing hydrogen from methane "is significantly more carbon intensive per unit of energy than coal. Mistaking fossil hydrogen from the hydraulic fracturing of shales for an environmentally sustainable energy pathway threatens to encourage energy policies that will dilute and potentially derail global efforts to head-off climate change due to the risk of diverting investment and focus from vehicle technologies that are economically compatible with renewable energy."<ref name=Cox2014>Cox, Julian.

A 2017 analysis published in ''Green Car Reports'' found that the best hydrogen fuel cell vehicles consume "more than three times more electricity per mile than an electric vehicle ... generate more greenhouse-gas emissions than other powertrain technologies ... [and have] very high fuel costs. ... Considering all the obstacles and requirements for new infrastructure (estimated to cost as much as $400 billion), fuel-cell vehicles seem likely to be a niche technology at best, with little impact on U.S. oil consumption.<ref name="greencarreports.com"/> In 2017, Michael Barnard, writing in ''[[Forbes]]'', listed the continuing disadvantages of hydrogen fuel cell cars and concluded that "by about 2008, it was very clear that hydrogen was and would be inferior to battery technology as a storage of energy for vehicles. [B]y 2025 the last hold outs should likely be retiring their fuel cell dreams.”<ref>Barnard, Michael.

The 95% of hydrogen still produced from fossil fuels releases carbon dioxide, and producing hydrogen from water is an energy-consuming process. Storing hydrogen requires more energy either to cool it down to the liquid state or to put it into tanks under high pressure, and delivering the hydrogen to fueling stations requires more energy and may release more carbon. The hydrogen needed to move a FCV a kilometer costs approximately eight times as much as the electricity needed to move a BEV the same distance.<ref>Ruffo, Gustavo Henrique.

[[File:Patent filings in the field of fuel cells by year of filing (1950–2020).png|thumb|Graph showing increase in fuel cell patent applications]]
Fuel cell [[patent]] fillings in the area of hydrogen fuel cells increased in the 1960s, partly due to [[NASA]]s space program; another increase in the 80s was driven by research for automobiles. This was followed by a surge in filings from 2000 to 2005 by inventors in Japan, US and South Korea. Since then, China has dominated patent fillings in the field, with a smaller number in Japan, Germany, South Korea and the US.<ref>{{Cite web |date=May 2022 |title=Patent Landscape Report – Hydrogen fuel cells in transportation |url=https://www.wipo.int/edocs/pubdocs/en/wipo-pub-1076-en-patent-landscape-report-hydrogen-fuel-cells-in-transportation.pdf |website=WIPO |page=17}}</ref> Between 2016 and 2020, annual filings, particularly for transportation applications, increased by a further 23%.<ref>{{Cite web |title=New Report: Patenting Booms for Clean &quotHydrogen Fuel Cell" Technologies for Transport |url=https://www.wipo.int/pressroom/en/articles/2022/article_0006.html |date=May 17, 2022 |access-date=September 13, 2022 |website=www.wipo.int}}</ref><ref>{{Cite web |date=May 2022 |title=Patent Landscape Report - Hydrogen fuel cells in transportation |url=https://www.wipo.int/edocs/pubdocs/en/wipo-pub-1076-en-patent-landscape-report-hydrogen-fuel-cells-in-transportation.pdf |website=[[WIPO]] |page=5}}</ref>

A 2022 [[World Intellectual Property Organization]] report argues that because heavy-duty vehicles, such as [[Heavy equipment|construction vehicles]], [[forklifts]], and [[Pushback (aviation)|airport tugs]] require a higher payload, the high energy density of hydrogen can make fuel cells a more advantageous solution than battery applications.<ref name=PLR7/>
