Provided is a method of preserving a PEFC stack, which is capable of controlling degradation of performance of the PEFC stack during a time period that elapses from when the stack is placed in an uninstalled state until it is placed in an installation position and is practically used. Provided is a preservation assembly of the 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. A method of preserving a PEFC stack that is provided with an oxidizing agent passage (30) having an inlet and an outlet and extending through a cathode and a reducing agent passage (40) having an inlet and an outlet and extending through an anode, comprising preserving the PEFC (200) stack in an uninstalled state in such a manner that an interior of the oxidizing agent passage (30) and an interior of the reducing agent passage (40) are set in a pressure-reduced state.
A method of preserving a polymer electrolyte fuel cell stack that 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 polymer electrolyte fuel cell stack being configured to generate power through an electrochemical reaction caused to occur in the cathode and the anode using an oxidizing agent supplied from the inlet of the oxidizing agent passage and a reducing agent supplied from the inlet of the reducing agent passage, the method comprising:
