    摘要： A fuel cell system includes a fuel cell that is subjected to a purge operation of supplying an inert gas to an anode and/or cathode upon shut-down of the fuel cell. The differential pressure ΔP is defined as ΔP=Pa−Pc where Pa is the pressure in an inlet-side flow path leading to the anode and Pc is the pressure in an inlet-side flow path leading to the cathode. The differential pressure during the purge operation is controlled such that the differential pressure during operation ΔPo and the differential pressure during the purge operation ΔPp satisfy the relation: 0

    摘要： A fuel cell having high operation performance and reliability is provided by optimizing the shape and properties of a gas diffusion layer and the dimensions of a gas flow channel. The fuel cell evenly supplies a reaction gas to the catalyst of a catalyst layer and promptly discharges excessive water generated therein. The gas diffusion layer of the MEA comprises a first section having a surface A coming in direct contact with a separator plate and a second section having a surface B facing the gas flow channel of the separator plate. The porosity of the first section is lower than the porosity of the second section, and the second section protrudes into the gas flow channel, which has sufficient width and depth for the protrusion of the gas diffusion layer, and the width of a rib formed by the gas flow channel is sufficiently narrow.
