Abstract

There is provided a fuel cell system. The fuel cell system comprises a fuel cell configured to generate electric power using a reactive gas; a compressor configured to compress the reactive gas and feed the compressed reactive gas to the fuel cell; a flow rate measurement unit configured to measure a flow rate of the reactive gas; a pressure measurement unit configured to measure a pressure of the compressed reactive gas; a power value acquirer configured to acquire a value of electric power consumed by the compressor; and a determiner configured to perform determination with regard to an abnormality of the fuel cell system and to provide an output indicating that an abnormality occurs. When the value of electric power corresponding to a value indicating the flow rate measured by the flow rate measurement unit exceeds a first set value, the determiner provides an output indicating that an abnormality occurs in the compressor in a case of (a1) where a value of the pressure measured by the pressure measurement unit corresponding to the value indicating the flow rate measured by the flow rate measurement unit is within a set range. The determiner is also configured to provide an output indicating that an abnormality occurs on a downstream side of the compressor in a case of (a2) where the value of the pressure corresponding to the value indicating the flow rate is out of the set range. This configuration allows for discrimination between an abnormality occurring in the compressor and an abnormality occurring on the downstream side of the compressor.
