    摘要: 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.

    摘要: A first separator has its surface which is designed to have a rectangular configuration. A fuel gas flow passage for making communication between a fuel gas inlet and a fuel gas outlet is provided on the surface. The fuel gas flow passage is designed to have a meandering configuration so that it extends in a long side direction and it turns back on a short side to allow a fuel gas to flow in the direction of the gravity. Accordingly, it is possible to effectively shorten a size in the height direction, and it is possible to obtain desired power generation performance with a simple structure.
