Abstract

A reaction gas supply apparatus for a fuel cell is able to adapt to various kinds of operating states, and can provide improved responsiveness with respect to a required output. The apparatus has: a compressorthat supplies pressurized air to a cathode electrode of a fuel cella hydrogen supply devicethat supplies hydrogen to an anode electrode of the fuel cella control devicethat regulates the pressure of the cathode electrode by controlling the compressoraccording to an operating state of the fuel celland a regulatorthat is applied with the air pressure of the cathode electrode as a reference pressure, and regulates the supply pressure to the anode electrode based on this air pressure. Moreover there is provided a pressure regulatorthat is capable of regulating the reference pressure that is applied to the regulatorby discharging air from an air flow passage for the air pressure that is applied to the regulator
