PROBLEM TO BE SOLVED: To provide a head and power supply unit that efficiently utilizes heat in electric power generator, not radiating the heat in a fuel cell to the outside with a cooling fan for. SOLUTION: It can shorten the length of the inner circulation circuit by involving a polymer electrolyte fuel cell 1, an inner circulation circuit and a first heat exchanger 14 into a fuel cell body unit 19 and also can reduce heat loss in a waste heat recovery pipe 17a, 17b and enhance a waste heat recovery efficiency by arranging a heat utilizing means 18 utilizing heat through an outside heat transportation medium heat exchanged by a first heat exchange means 14 and the waste heat recovery pipes 17a, 17b. Because of reducing a total amount of an internal heat transportation medium, it can economize by constituting the internal heat transportation medium into antifreeze liquid and the external heat transportation medium within the waste heat recovery pipes into water, etc. |
