Claim:
1. A fuel cell that includes a membrane-electrode assembly and separators disposed at both sides of the membrane-electrode assembly, the fuel cell comprising: a conductive microporous body formed on a reaction surface of the separator corresponding to the membrane-electrode assembly and is configured to supply a reaction gas to the membrane-electrode assembly, wherein the separator has inlet and outlet manifolds for the reaction gas to flow into and out of and a channel unit connected with the inlet manifold and the outlet manifold and configured to guide a reaction gas to the reaction surface, wherein the channel unit guides the reaction gas flowing into the inlet manifold to the conductive microporous body of the reaction surface and allows the reaction gas passing through the conductive microporous body to flow to the outlet manifold, and wherein separation walls that divide the conductive microporous body into several sections are formed on the reaction surface of the separator, the separation walls are formed in the shapes of grooves on the side opposite to the reaction surface and protrude toward the reaction surface, and the grooves are formed as cooling passages through which a coolant flows.
