FUEL CELL SYSTEM AND CONTROL METHOD THEREOF

摘要

A fuel cell system includes: a fuel cell (20); an oxidant gas supply unit (30) configured to supply an oxidant gas to a cathode electrode of the fuel cell (20); and a gas pressure control unit (60) configured to detect as a gas pressure sensitivity a ratio of variation in an output of the fuel cell (20) to variation in the pressure of the oxidant gas, specify a correspondence relationship between the pressure of the oxidant gas and the output of the fuel cell (20) on the basis of the detected gas pressure sensitivity, and control the pressure of the oxidant gas on the basis of the specified correspondence relationship.
