<P>PROBLEM TO BE SOLVED: To provide a fuel cell system accurately estimating the remaining amount of hydrogen by correctly estimating the amount of hydrogen consumed in the whole system by correctly estimating the amount of exhaust hydrogen. <P>SOLUTION: A hydrogen mass consumed by power generation of a fuel cell 1 is estimated with a power generation amount detecting part 41 and a consumed hydrogen mass calculation part 42. Temperature of the whole exhausted gas burned with a combustion device is found from a detected value of an exhausted hydrogen temperature sensor 32 by an oxidation/combustion fluid whole temperature calculating part 43, and the mass of the whole exhausted gas burned with the combustion device is found from information obtained from an air supply compressor 22 and a circulation hydrogen exhausted valve 14 with an oxidation/combustion fluid whole mass calculating part 46. The hydrogen mass contained in the exhaust gas is found by an oxidation/combustion hydrogen mass calculating part 48 by finding the total amount of heat in the combustion device with a total amount of heat calculating part 47, the consumed hydrogen mass of the whole system is found by adding the hydrogen mass consumed by power generation in the fuel cell 1 and the exhausted hydrogen mass, and the remaining hydrogen mass in a hydrogen storage device is found. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
