Patent ID: 8647786

Claim:
A fuel cell system mounted on a moving body, the fuel cell comprising: a cell stack formed by stacking a plurality of unit cells, each having a fuel electrode and an oxidizing electrode; a refrigerant inlet provided in a lower end side portion of the cell stack, for introducing a refrigerant to be used for heat exchange with the unit cells into the inside of the cell stack; a refrigerant outlet provided in an upper end portion of the cell stack, for discharging the refrigerant used for heat exchange with the unit cells to the outside of the cell stack; and a reactant gas manifold penetrating along a unit cell stacking direction, for supplying and discharging a reactant gas used for cell reaction in the fuel electrode and the oxidizing electrode, wherein: a pair of cell stacks are positioned symmetrically to each other with respect to a plane perpendicular to a horizontal plane; and the pair of cell stacks are positioned so as to be inclined with respect to the horizontal plane when viewed from a direction perpendicular to the unit cell stacking direction such that a plane defined by a unit cell stacking direction of one cell stack in the pair of cell stacks is inclined with respect to a plane defined by a unit cell stacking direction of the other cell stack in the pair of cell stacks, and the unit cell stacking directions of the cell stacks are in a V shape or a Λ shape when viewed from the direction perpendicular to the unit cell stacking direction.
