Abstract: Disclosed is a fuel cell with a porous material-gasket integrated structure, which can facilitate the flow of gas and water by stacking a porous material-gasket integrated structure, in which a porous material and a gasket are integrally molded, on a separator. In particular, the present invention provides a fuel cell with a porous material-gasket integrated structure, in which a porous material and a gasket are integrally molded and stacked on a separator such that the porous material is located between a manifold, through which gas is supplied, and a reaction surface, where an electrochemical reaction takes place, so as to serve as a diffuser for gas fed through the manifold.
