Electric traction motor FCEV : Using power from the fuel cell and the traction battery pack, this motor drives the vehicle's wheels. Some vehicles use motor generators that perform both the drive and regeneration functions.
Fuel cell stack: An assembly of individual membrane electrodes that use hydrogen and oxygen to produce electricity. Fuel filler: A nozzle from a fuel dispenser attaches to the receptacle on the vehicle to fill the tank. Still, the impact is still less than gasoline-powered counterparts. Hydrogen power has been on the market for years but in an extremely limited capacity. There are currently 39 public hydrogen fueling stations in California with another 25 in development , along with a couple in Hawaii.
Now the East Coast is getting its own infrastructure. Hydrogen is more established in the commercial market. There are more than 23, fuel cell-powered forklifts in operation at warehouses and distribution centers across the U.
There are dozens of fuel cell buses in use or planned in Ohio, Michigan, Illinois and Massachusetts, as well as California. Consumer hydrogen refueling stations are increasing throughout the world. Toyota and Honda are teaming up with the government in Quebec to build hydrogen infrastructure in Montreal this year, and even oil-rich Saudi Arabia is getting its first station. Toyota , the world's second-largest automaker, is the largest player in the U.
Its Mirai — a hydrogen fuel cell family car — has found 5, buyers since it was introduced in the fall of Russ Koble, a spokesman in Toyota's environmental and advanced technology group, said the company expects sales to increase as more fueling stations open. Toyota says the scalability of hydrogen fuel cell technology also has led to two applications for California feasibility studies in another area of interest to Tesla: semi-trailer trucks.
Honda also has made a big commitment to hydrogen. Honda only offers the Clarity Fuel Cell in California for lease — it offers battery electric power and hybrid versions of the car for lease or sale. Out of the 20, total Claritys sold or leased in , were fuel cell variants, were battery-electrics, and 18, were the plug-in hybrid. Honda and Toyota have teamed up with a subsidiary of Shell Oil to build new hydrogen fueling stations in California. Two have been built thus far, and five are in the works, Kumaratne said.
The company is advocating for stations in the Northeastern United States, with several in development. Department of Energy DOE is working closely with its national laboratories, universities, and industry partners to overcome critical technical barriers to fuel cell development.
Cost, performance, and durability are still key challenges in the fuel cell industry. View related links that provide details about DOE-funded fuel cell activities. A major update to this document is in progress. How Fuel Cells Work Fuel cells work like batteries, but they do not run down or need recharging.

However, with many very real benefits, hydrogen fuel cells look set to be part of the power generation future in some form.
Renewable energy comes from sources or processes that are constantly replenished. These sources of energy include solar energy, wind energy, geothermal energy, and hydroelectric power.

Advantages and disadvantages FAQs Conclusion. The process by which a fuel cell works can be summarised as follows: Hydrogen atoms enter at the anode, while oxygen is fed to the cathode The hydrogen atoms are separated into protons and electrons at the anode The now positively charged protons pass through the membrane or electrolyte to the cathode, with the negatively charged electrons take a different route as they are forced through a circuit to generate electricity After passing through the circuit and the membrane accordingly, the electrons and protons meet at the cathode where they combine with oxygen to produce heat and water as by-products.
Cost The cost of fuel cells can be high given the use of platinum as one of the largest component materials. There is work underway to find non-platinum catalyst approaches 2. Hydrogen Extraction The extraction of hydrogen for use in fuel cells can take a lot of energy to achieve, undermining the green benefits of fuel cell use 3.
Infrastructure There is a need to create the infrastructure to support the growth in fuel cell use, including retrofitting vehicles 4. Safety The flammable nature of hydrogen poses evident safety concerns for its widespread use Find out more about the pros and cons here FAQs What are they used for?
Here is a selection of fuel cell uses: 1. Power Fuel cells act as power sources for a variety of commercial, industrial and residential applications. Cogeneration Fuel cells can be made even more efficient through cogeneration. Transport Fuel cells can be used for a variety of transport applications, from automobiles to buses, ships, trains and aircraft. Portable Power Portable fuel cell systems are classified as weighing less than 10kg and producing under 5kW of power.
Other Applications The uses listed above are just some of the examples of where fuel cells could be used. Who Invented Hydrogen Fuel Cells? How Long Do They Last? Are They Dangerous? Conclusion Hydrogen fuel cells have been used for many decades for a wide range of applications, from small electronic devices to vehicles.
