摘要： A preservation assembly of a PEFC stack which is capable of sufficiently inhibiting degradation of performance of the PEFC stack particularly during a time period that elapses from when the stack is placed in the uninstalled state until it is placed in the installation position and is practically used. The PEFC stack is provided with an oxidizing agent passage having an inlet and an outlet and extending through a cathode and a reducing agent passage having an inlet and an outlet and extending through an anode. The PEFC stack is preserved in an uninstalled state in such a manner that an interior of the oxidizing agent passage and an interior of the reducing agent passage are set in a pressure-reduced state.

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.
