An electrically conductive porous body for a fuel cell has a porous metal body and an electrically conductive layer that is disposed on one surface side of the porous metal body and that has gas permeability, wherein at least a part of the one surface side of the porous metal body is buried into one surface side of the electrically conductive layer, and wherein the flatness of the other surface side of the electrically conductive layer, into which the porous metal body is not buried, is higher than the flatness of the one surface side of the porous metal body. Sufficient contact surface area is obtained between the porous metal body and the membrane electrode assembly, without applying pressure to the porous metal body. It is therefore possible to achieve a low contact resistance with the membrane electrode assembly, without causing a change in the internal condition of the porous metal body. |
