Abstract

Each of cooling medium flow passages provided for a first separator includes single main flow passage grooves communicating with a cooling medium inlet and a cooling medium outlet respectively, and branched flow passage grooves formed and branched between the main flow passage grooves. Accordingly, it is possible to greatly decrease the flow passage length. Therefore, it is possible to effectively avoid the occurrence of flow passage pressure loss in the superficial direction of the first separator, and it is possible to improve the system efficiency of the power generation.
