PURPOSE:To effectively cool by inserting a heat pipe with fins into a base body pipe, bringing the fins into contact with the inner surface of the base body pipe, and using gaps between the fins as gas passage. CONSTITUTION:A heat pipe 40 with fins is inserted into a base body pipe 12, and the fins 46 are brought into contact with the inner surface of the base body pipe 12. The fins 46 are formed in a spiral or disk shape and gas passages 48 are opened on the fins. Heat with high temperature generated in a fuel cell 10 is conducted to the heat pipe 40 by radiation and conduction through the fins 46, and is exhausted outside or distributed uniformly. Thereby, power generating efficiency of the fuel cell is increased as a whole. |
