摘要： A polymer electrolyte fuel cell system of the present invention comprises cells 10, a stack 100, a temperature control device (160, 140, 40, 41), an anode gas supplier 110, a cathode gas supplier 120, and a controller 300. When a power generation output of the stack 100 is reduced, the controller 300 controls the anode gas supplier 110 and the cathode gas supplier 120 to reduce a supply amount of the anode gas and a supply amount of the cathode gas, and controls at least one of the anode gas supplier 110, the cathode gas supplier 120, and the temperature control device 100 to cause a dew point temperature of a gas supplied to at least one of the anode gas channels and the cathode gas channels to be higher relative the temperature of the stack 100 so that the gas becomes supersaturated or more supersaturated than prior to causing the dew point temperature of the gas to be higher.

摘要： A close attachment region is provided on the outer side relative to an outer edge portion of a gas diffusion layer and on the inner side relative to the inner edge portion of a gasket as seen from the thickness direction of a polymer electrolyte membrane, such that separators and a frame member are closely attached to each other. Thus, it becomes possible to suppress an increase in the manufacturing cost and a reduction in the power generation performance, which is attributed to the impurity eluted from the gasket and flowing toward the gas diffusion layer.
