Fuel cells use hydrogen (or hydrogen-rich fuel) and oxygen to create electricity through an electrochemical process. A single fuel cell consists of an electrolyte and two catalyst-coated electrodes (a porous anode and a cathode).

As the technology has evolved, researchers have developed different fuel cell designs to meet different needs. Fuel cells are classified primarily by the type of electrolyte they use. This determines, for example, the kind of chemical reactions that take place within the cell, the type of catalysts required, and the temperature range in which the cell operates. These design and operating characteristics, in turn, determine which type of fuel cell is best for which application.
The five most common types of hydrogen fuel cells are:
○ Polymer electrolyte membrane (PEM)
○ Phosphoric acid (PAFC)
○ Solid oxide (SOFC)
○ Molten carbonate (MCFC)
○ Alkaline (AFC)
