Abstract

A polymer electrolyte fuel cell system with a polymer electrolyte fuel cell is made up of a cell main body, a mixture generator for generating a gas-liquid mixture by mixing fuel gas which has been supplied from a fuel gas supply with water, and a means for supplying the gas-liquid mixture to the anode-side channels. The gas-liquid mixture allows the solid-polymer film to be moistened without humidifying fuel gas and oxidant gas with a humidifier, and the cell main body to be cooled down without providing a cooling channel therein.
