A fuel cell is an electrochemical cell that converts the chemical energy of a fuel and an oxidizing agent into electricity through a pair of redox reactions. Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from substances that are already present in the battery. Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied.
Ballard Power Systems Inc. is a developer and manufacturer of proton exchange membrane (PEM) fuel cell products for markets such as heavy-duty motive, portable power, material handling as well as engineering services. Ballard has designed and shipped over 400 MW of fuel cell products to date.
Proton-exchange membrane fuel cells (PEMFC), also known as polymer electrolyte membrane (PEM) fuel cells, are a type of fuel cell being developed mainly for transport applications, as well as for stationary fuel-cell applications and portable fuel-cell applications. Their distinguishing features include lower temperature/pressure ranges and a special proton-conducting polymer electrolyte membrane. PEMFCs generate electricity and operate on the opposite principle to PEM electrolysis, which consumes electricity. They are a leading candidate to replace the aging alkaline fuel-cell technology, which was used in the Space Shuttle.
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 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 vehicles. As compared with internal combustion vehicles, hydrogen vehicles centralize pollutants at the site of the hydrogen production, where hydrogen is typically derived from reformed natural gas. Transporting and storing hydrogen may also create pollutants. Fuel cells have been used in various kinds of vehicles including forklifts, especially in indoor applications where their clean emissions are important to air quality, and in space applications. Fuel cells are being developed and tested in trucks, buses, boats, ships, motorcycles and bicycles, among other kinds of vehicles.
The Honda Clarity is a nameplate used by Honda on alternative fuel vehicles. It was initially used only on hydrogen fuel-cell electric vehicles such as the 2008 Honda FCX Clarity, but in 2017 the nameplate was expanded to include the battery-electric Honda Clarity Electric and the plug-in hybrid electric Honda Clarity Plug-in Hybrid, in addition to the next generation Honda Clarity Fuel Cell. Clarity production ended in August 2021 with US leases for the fuel cell variant continuing through to 2022.
Micro combined heat and power, micro-CHP, μCHP or mCHP is an extension of the idea of cogeneration to the single/multi family home or small office building in the range of up to 50 kW. Usual technologies for the production of heat and power in one common process are e.g. internal combustion engines, micro gas turbines, stirling engines or fuel cells.
A proton-exchange membrane, or polymer-electrolyte membrane (PEM), is a semipermeable membrane generally made from ionomers and designed to conduct protons while acting as an electronic insulator and reactant barrier, e.g. to oxygen and hydrogen gas. This is their essential function when incorporated into a membrane electrode assembly (MEA) of a proton-exchange membrane fuel cell or of a proton-exchange membrane electrolyser: separation of reactants and transport of protons while blocking a direct electronic pathway through the membrane.
Formic acid fuel cells (direct formic acid fuel cells or DFAFCs) are a subcategory of direct liquid-feed fuel cells (DLFCs), in which the liquid fuel is directly oxidized (electrochemically) at the anode instead of reforming to produce hydrogen. Formic acid-based fuel cells represent a promising energy supply system in terms of high volumetric energy density, theoretical energy efficiency, and theoretical open-circuit voltage. They are also able to overcome certain problems inherent to traditional hydrogen (H2) feed fuel cells such as safe handling, storage, and H2 transportation.
UTC Power was a fuel cell company based in South Windsor, Connecticut. It was part of United Technologies Corporation; it was purchased by ClearEdge Power in February 2013. The company specialized in fuel cells for buildings, buses and automobiles. It has also developed fuel cells for space and submarine applications in the past.
Reformed Methanol Fuel Cell (RMFC) or Indirect Methanol Fuel Cell (IMFC) systems are a subcategory of proton-exchange fuel cells where, the fuel, methanol (CH3OH), is reformed, before being fed into the fuel cell.
The canal boat Ross Barlow is a hybrid hydrogen narrowboat, power-assisted by an electric motor whose electricity is supplied by a fuel cell or a battery. It debuted on 21 September 2007.
Stationary fuel-cell applications are applications for fuel cells that are either connected to the electric grid to provide supplemental power and as emergency power system for critical areas, or installed as a grid-independent generator for on-site service.
The Riversimple Urban Car is a conceptual open source hydrogen fuel cell vehicle that was proposed by Hugo Spowers' company, Riversimple, in 2009. Their latest model, the Rasa, was unveiled on 17 February 2016.
The principle of a fuel cell was discovered by Christian Friedrich Schönbein in 1838, and the first fuel cell was constructed by Sir William Robert Grove in 1839. The fuel cells made at this time were most similar to today's phosphoric acid fuel cells. Most hydrogen fuel cells today are of the proton exchange membrane (PEM) type. A PEM converts the chemical energy released during the electrochemical reaction of hydrogen and oxygen into electrical energy. The Hydrogen Research, Development, and Demonstration Act of 1990 and Energy Policy Act of 1992 were the first national legislative articles that called for large-scale hydrogen demonstration, development, and research programs. A five-year program was conducted that investigated the production of hydrogen from renewable energy sources and the feasibility of existing natural gas pipelines to carry hydrogen. It also called for the research into hydrogen storage systems for electric vehicles and the development of fuel cells suitable to power an electric motor vehicle.

High Temperature Proton Exchange Membrane fuel cells (HT-PEMFC), also known as High Temperature Polymer Electrolyte Membrane fuel cells, are a type of PEM fuel cells which can be operated at temperatures between 120 and 200°C. HT-PEM fuel cells are used for both stationary and portable applications. The HT-PEM fuel cell is usually supplied with hydrogen-rich gas like reformate gas formed by reforming of methanol, ethanol, natural gas or LPG.
