摘要： PROBLEM TO BE SOLVED: To prevent the performance of a fuel battery cell from being degraded by checking whether a raw material fuel and steam are appropriately mixed in a fuel battery.
SOLUTION: The fuel cell system 1 includes a fuel battery cell 13 which generates power by chemical reaction of an oxidizer and a steam-reformed fuel through a solid electrolyte, a limiting current type humidity sensor 31 arranged in a fuel supply passage 25 for supplying fuel to the anode of the fuel battery cell 13, and an all-region air-fuel ratio sensor 33 arranged in a fuel exhaust passage 27 for discharging the spent fuel used in the anode of the fuel battery cell 13. Thereby, since the steam volume in the fuel supply passage 25 can be detected using the limiting current type humidity sensor 31 and the all-region air-fuel ratio sensor 33, it can be detected excellently whether steam is appropriately added to the fuel supplied to the anode of the fuel battery cell 13.

摘要： PROBLEM TO BE SOLVED: To provide a controlling apparatus and a controlling method of a moisture sensor for accurately detecting moisture for a long time by appropriately executing heated cleaning. SOLUTION: A heater (17) is energized to heat a moisture-sensing element section (3) in a temperature range of 500-800°C in a time zone where moisture is not measured while an internal engine is operating. Additionally, after the internal engine stops, the moisture-sensing element section (3) is heated for specific time, for example approximately several seconds - 10 minutes within a range of 500-1200°C. In this case, heating temperature and heating time are set according to the deterioration of a moisture sensor (1). Further, at timing where no voltages are applied to the heater (17), the resistance of a temperature sensor (19) is measured, and the feedback control of the heater (17) is made so that the resistance becomes constant according to the resistance.
