FUEL CELL EQUIPPED WITH HEAT SHIELDING CONTAINER

PROBLEM TO BE SOLVED: To enable to handle safely a power generator by granting a heat exchange function to a container itself housing a power generating stack having an exothermic portion of a fuel cell, and by removing excess heat from the power generator, while maintaining the power generating equipment such as a stack in high temperature without deteriorating power generation efficiency. SOLUTION: The stack 5 is mainly constructed of a heat shielding container 3 which is formed in lamination of an outer case material 23 made of a metallic wall 22 having ventilation holes 21 communicating between the outside and inside opened at a plurality of places in order to house a ceramic burner 6 and a ceramic heat exchanger 7 or the like and a porous material 24 having ventilation capacity arranged inside the metallic wall 22, and a heat exchange gap 25 at the surrounding of the stack 5. Cooling air is introduced from each ventilation hole 21 of the heat shield container 3 and the cooling air is circulated in the heat exchange gap 25, and the reaction heat generated in the stack 5 is heat exchanged.
