Fuel cell

A fuel cell comprising a cell forming member which is sandwiched between a pair of separators and which includes a power generating section including an electrolyte membrane joined between an anode and a cathode, and manifolds which are formed in the cell forming member and the separators at such a position that the manifolds confront one another, and which are arranged to allow inflow and outflow of an hydrogen containing gas and an oxygen containing gas separately from each other to the anode and cathode,

• the manifold of the cell forming member being formed with an inflow preventing portion to prevent inflow of a liquid water remaining in the manifold of the cell forming member into a power generating portion;
• wherein the manifold of the cell forming member includes a bottom located on a lower side in a gravity direction, and the inflow preventing portion is formed by forming a part of the bottom on a power generating portion's side on an upper side in the gravity direction as compared to a part of the bottom on an opposite side opposite to the power generating portion.

The fuel cell as recited in claim 9, wherein the inflow preventing portion is provided in at least one of a plurality of the manifolds.

The fuel cell as recited in claim 11, wherein the inflow preventing portion is provided in one of the manifolds which is adjacent to the anode and which is provided for outflow of the hydrogen containing gas.

The fuel cell as recited in claim 11, wherein the inflow preventing portion is provided in one of the manifolds which is adjacent to the cathode and which is provided for outflow of the oxygen containing gas.
