ABSTRACT:
A separator for use in solid polymer fuel cells has porous areas, dense areas and gas flow channels. The flow channels are defined by flow channel surfaces, some or all of which are formed in the porous areas. The gas flow channels are not readily obstructed by water that forms during power generation. The separator has an adequate strength for use in fuel cells and a low contact resistance.
