    摘要： A preservation assembly of a polymer electrolyte fuel cell stack is provided. The assembly includes an uninstalled polymer electrolyte fuel cell stack and sealing units. The uninstalled polymer electrolyte fuel cell 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 sealing units include sealing plugs or containers and are configured to seal the inlet and the outlet of the oxidizing agent passage within which an oxygen concentration has been decreased and to seal the inlet and the outlet of the reducing agent passage within which the oxygen concentration has been decreased. The uninstalled polymer electrolyte fuel cell stack is in a state before an assembled polymer electrolyte fuel cell stack is incorporated into a fuel cell system.
