A unit cell has a membrane electrode assembly. The membrane electrode assembly includes a cathode, and an anode, and a solid polymer electrolyte fuel cell interposed between the cathode and the anode. The membrane electrode assembly is interposed between a first separator and a second separator. A thin cooling plate is interposed between the second separator and another first separator. A first coolant flow passage and a second coolant flow passage are formed on both surfaces of the cooling plate. The coolant flows along one surface of the cooling plate, and turns back at an end of the cooling plate to flow along the other surface of the cooling plate.
A fuel cell stack formed by stacking a plurality of assemblies each interposed between separators, each of said assemblies including a cathode, an anode, and an electrolyte interposed between said cathode and said anode, said fuel cell stack comprising:
