ABSTRACT
Polymer electrolyte membrane fuel cell (PEMFC) is one of the most promising energy conversion devices in terms of com mercialization for use in transportation and distributed power generation systems. PEMFC offers attractive features such as high power density, modularity, solidstate construction, low operating temperature and pressure, longer lifetime, minimal emissions, quick startup, negligible noise, and high chemical to electrical energy conversion efficiency. PEMFC may gener ate power in the range of watts to kilowatts.
