摘要： PROBLEM TO BE SOLVED: To provide a technique for preventing the occurrence of failure of a fuel battery system owing to the irreversible deterioration of a film-electrode assembly.SOLUTION: A fuel battery system 100 comprises: a fuel battery 10 having a film-electrode assembly; a control part 20 serving as a power-generator-fatigue-management part 22; and a power-generator-fatigue-notice part 74. The power-generator fatigue management part 22 detects a stress produced in the film-electrode assembly of the fuel battery 10 on the basis of a value measured by a film-resistance detector 70. Each time the power-generator fatigue management part 22 detects a stress produced in the film-electrode assembly, it updates a degree of accumulated fatigue showing the fatigue accumulated on the film-electrode assembly. When the degree of accumulated fatigue increases to or above a predetermined value, the power-generator fatigue management part 22 causes the power-generator-fatigue-notice part 74 to notify the limit of use of the film-electrode assembly.

摘要： PROBLEM TO BE SOLVED: To provide a cooling system for a fuel cell mounting vehicle capable of suitably carrying out cooling according to a driving state of a vehicle. SOLUTION: In the vehicular cooling system 10, an air conditioner radiator 42 on an upstream side of vehicle speed wind, and a fuel cell radiator 62 on a downstream side are disposed so as to be superimposed with each other in a flow passage of the vehicle speed wind. A controlling computer 80 of the cooling system 10 judges whether the temperature of a fuel cell stack 32 is not less than a predetermined value or not. As a result of that, if not less than the predetermined value TH, as a radiator mounting variable control, an installation position of a heat exchanger unit 42a constituting the air conditioner radiator 42 or installation positions of the heat exchanger unit 42a and a heat exchanger unit 42b are moved toward an upper surface direction, thereby increasing the vehicle speed wind led to the fuel cell radiator 62 without raising temperature by the air conditioner radiator 42 and lowering wind speed.
