Claim Text:
1. A fuel cell, comprising: a membrane electrode assembly comprising an electrolyte membrane and catalyst layers joined on both sides of the electrolyte membrane; and a pair of separators disposed at both sides of the membrane electrode assembly to respectively form gas flow spaces where two types of power generation gases flow, wherein: an electrically conductive porous substrate and a gas flow path dividing member are disposed in at least one of the gas flow spaces defined on both sides of the membrane electrode assembly, the electrically conductive porous substrate is folded in a corrugated shape, the gas flow path dividing member dividing a gas flow space into a plurality of gas flow paths is substantially parallel to a flow direction of the power generation gases, and folded portions of the electrically conductive porous substrate extending into the gas flow paths further dividing the gas flow paths.
