FUEL CELL SYSTEM, ABNORMALITY DETECTION METHOD FOR THE SYSTEM, AND MOVABLE BODY

摘要

A fuel cell system in which detecting accuracy of an abnormality, such as fuel gas leakage, in a gas passage can be improved. When a control section (50) of a fuel cell system (10) detects fuel gas leakage, it forms adjacent closed regions of space by opening and closing a valve (H200) etc. arranged in a fuel gas circulation/supply system. The control section (50) obtains the amount of variation in the amount of fuel gas after the lapse of predetermined time based on the pressure and the temperature of each region of space, and determines whether there is fuel gas leakage from the obtained amount of variation in the amount of the fuel gas.
