Claim:
1. A fuel cell comprising: a pair of separators; a cell forming member sandwiched between the pair of separators, the cell forming member including a power generating portion including an electrolyte membrane joined between an anode and a cathode; manifolds formed in the cell forming member and the pair of separators at such a position that the manifolds confront one another, the manifolds being arranged to allow inflow and outflow of a hydrogen containing gas and an oxygen containing gas separately from each other to the anode and cathode; and a diffuser arrangement region extending from the manifolds to the power generating portion, wherein a manifold of the cell forming member includes an inflow preventing portion configured to prevent an inflow of a liquid water remaining in the manifold of the cell forming member into the power generating portion, wherein the inflow preventing portion is formed without bulging into the diffuser arrangement region, wherein the manifold of the cell forming member includes a bottom located on a lower side of the manifold in a gravity direction, the bottom having an inner portion and an outer portion, the inner portion located closer to the power generating portion than the outer portion, and wherein the inflow preventing portion is formed by forming the bottom such that the inner portion of the bottom is located at a higher position in the gravity direction than the outer portion of the bottom.
