A proton exchange membrane fuel cell transforms the chemical energy liberated during the electrochemical reaction of hydrogen and oxygen to electrical energy, as opposed to the direct combustion of hydrogen and oxygen gases to produce thermal energy. A stream of hydrogen is delivered to the anode side of the MEA.
The resulting hydrogen is an energy carrier that can power a car by reacting with oxygen from the air to create water, either through burning in a combustion engine or catalyzed to produce electricity in a fuel cell. Hydrogen fuel enhancement, where a mixture of hydrogen and conventional hydrocarbon fuel is burned in an internal combustion ...
A fuel cell is an electrochemical energy conversion device. Fuel cells differ from batteries in that they are designed for continuous replenishment of the reactants consumed. This is a partial list of companies currently producing commercially available fuel cell systems for use in residential, commercial, or industrial settings.
Fuel cell vehicle. 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.
Fuel cell. Demonstration model of a direct methanol fuel cell (black layered cube) in its enclosure. Scheme of a proton-conducting fuel cell. A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) [1] into electricity through a pair of redox reactions. [2]
A regenerative fuel cell or reverse fuel cell (RFC) is a fuel cell run in reverse mode, which consumes electricity and chemical B to produce chemical A. By definition, the process of any fuel cell could be reversed. [ 1] However, a given device is usually optimized for operating in one mode and may not be built in such a way that it can be ...
The FV-E991 series (FV-E991系), nicknamed HYBARI, is a hydrogen fuel cell electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East) from 2022. [2] [3] This series will be used as a test unit to collect data for future development and deployment of fuel cell vehicles. Starting in 2021, JR East will conduct trials ...
In contrast to indirect methanol fuel cells, where methanol is reacted to hydrogen by steam reforming, DMFCs use a methanol solution (usually around 1M, i.e. about 3% in mass) to carry the reactant into the cell; common operating temperatures are in the range 50 to 120 °C (122 to 248 °F), where high temperatures are usually pressurized.
