PROBLEM TO BE SOLVED: To provide a fuel cell system that has a high reliability and good efficiency. SOLUTION: The cooling water, which absorbs heat generated at the fuel cell 1 and radiates at the radiator 15, is circulated by a pump 16 and sent to a detector 17. The detector 17 detects whether or not there exists microbial organism in the cooling water and if it obtains the result that there exists, it gives an instruction to the germicidal device 18 for killing the microbial organism. The germicidal device 18 kills the microbial organism based on this instruction by irradiating ultraviolet rays. Accordingly, such a state that circulation system of the cooling water is clogged by the microbial organism or that the performance of each equipment is deteriorated can be avoided in advance. On the other hand, if the result is obtained that there does not exists microbial organism, the germicidal device 18 does not operate. Hence it becomes possible to avoid the electric power being wasted by an unnecessary irradiation of ultraviolet rays. |
