Patent ID: 8470490

Claim:
A fuel cell stack comprising a cell stack in which a plurality of fuel battery single cells are stacked, a pair of end plates which sandwich the cell stack from respective sides in a stack direction, and a system component which is mounted on one end plate, and in which there is formed a manifold that extends in and through the cell stack in the stack direction and for supplying and discharging a fuel gas or an oxidizing agent gas for each of the fuel battery single cells, wherein the one end plate has a stack-facing surface which faces the cell stack and a system component mounting surface on a side opposite of the stack facing surface, and a system component mounting portion for mounting the system component being formed in a projected manner on the system component mounting surface, and the system component mounting portion has a trapezoidal side surface with a tip surface of the system component mounting portion having an inclination angle with respect to the stack-facing surface so that, when the fuel cell stack is placed such that the manifold has a downward inclination toward the one end plate, the surface of the system component mounting portion is oriented along a vertical direction, wherein the system component includes at least a pump and a pipe.
