A hydrogen fuel cell is a device that converts the chemical energy of hydrogen and oxygen into electrical energy, producing water as a byproduct.
Hydrogen Fuel Cell cheat sheet for homework
Proton Exchange Membrane (PEM) fuel cells: These are a type of hydrogen fuel cell that use an electrolyte membrane to conduct protons and separate the reactant gases.
These are another type of hydrogen fuel cell that use phosphoric acid as an electrolyte to facilitate the electrochemical reactions.
Electrolysis: The process of using electricity to split water molecules into hydrogen and oxygen gases, which can then be used in a fuel cell.
