62 Fuel Cell Types

Five principle types of fuel cells are currently in various stages of commercial availability or undergoing research, development, and demonstration for distributed generation applications. These five fuel cell types are significantly different from each other in many respects; however, the key distinguishing feature is the electrolyte material, which is generally used to identify each of the five fuel cell types: (1) alkaline fuel cell (AFC), (2) molten carbonate fuel cell (MCFC), (3) phosphoric acid fuel cell (PAFC), (4) proton exchange membrane fuel cell (PEMFC), and (5) solid oxide fuel cell (SOFC).
