چکیده

Fuel cells are electrochemical devices which convert chemical energy of a reacting fuel directly into electricity with high efficiency and no pollution. Proton Exchange/ Polymer Electrolyte Membrane (PEM) fuel cells are likely to be among one of the most promising energy sources for transportation, heating and power generation. Some of the key materials used in PEM fuel cells are catalysts, membranes, gas diffusion layers (GDLs), and bipolar plates. There is a need for the development of woven fabric GDLs which can be tailored for continuous commercial scale production of membrane electrode assemblies (MEAs) to reduce the labor cost of fuel cell manufacture. At the University of New Hampshire research is being conducted on the development of fabric GDL made of carbon fibers ( called UNH GDL).
