PROBLEM TO BE SOLVED: To provide a fuel cell power generator with a cooling water circulating and supplying system to supply stably cooling water to a fuel cell main body, having a reduced device height, and suitable as indoor type. SOLUTION: In this power generator in which a two-phase flow discharged from a cell cooling mechanism 1c of a fuel cell main body 1 is introduced into a steam separator 2 to separate steam from cooling water, and in which the resulting cooling water is circulatedly supplied again to the cooling mechanism 1c by a cooling water circulation-supplying system, a circulating circuit provided with a flow control valve 4 and a heat exchanger 5 is assembled in between a delivery side and a suction side of a cooling water circulating pump 3 of the cooling water circulation-supplying system, the flow control valve 4 is controlled by a detected temperature of a thermometer 6, and a flow rate of the cooling water flowing in the circulating circuit is regulated thereby to hold a cooling water temperature in the suction side of the circulating pump 3 at a low temperature all the time. |
