Abstract
A fuel cell systemincludes: a fuel cellfor generating a power by causing an electrochemical reaction between an oxidant gas supplied to an oxidant electrodeand a fuel gas supplied to a fuel electrode; a fuel gas supplier HS for supplying the fuel gas to the fuel electrode; and a controllerfor controlling the fuel gas supplier HS to thereby supply the fuel gas to the fuel electrode, the controllerbeing configured to implement a pressure change when an outlet of the fuel electrodeside is closed, wherein based on a first pressure change pattern for implementing the pressure change at a first pressure width ΔP, the controllerperiodically changes a pressure of the fuel gas at the fuel electrode
