Abstract:
1. A solid polymer electrolyte fuel cell assembly, comprising a plurality of unit cells stacked to each other, said unit cells each having a unified body including an anode, a cathode, and a solid polymer electrolyte membrane disposed between said anode and said cathode, wherein a plurality of reaction gas passages are formed parallel in said cell assembly, in a direction in which said unit cells are stacked, for allowing at least one of a fuel gas and an oxidizing gas to flow through said unit cells in a same direction, wherein coolant passages for cooling said cell assembly are formed on both sides of said plurality of unit cells in the stacking direction of said unit cells, wherein each of said coolant passages extends linearly alone a plane direction of said unit cells, and wherein the coolant and the oxidizing gas flow in a same direction.
