ACTIVATING METHOD OF FUEL CELL FOR PERFORMANCE RECOVERY

摘要

A method of activating a fuel cell stack for performance recovery that can restore performance by activating a fuel cell stack with degraded performance will be described. A method of activating a fuel cell stack for performance recovery according to the present invention includes the steps of: (a) injecting hydrogen as a reactant gas into the anode of the fuel cell stack for performance recovery on the fuel cell stack whose performance has deteriorated due to long- ; (b) applying current to the fuel cell stack while blocking air flowing into the cathode of the fuel cell stack; (c) reducing the metal oxide film of the cathode by allowing hydrogen to pass from the anode of the fuel cell stack to the cathode by the partial pressure difference due to application of current to the fuel cell stack; And (d) releasing a current from the fuel cell stack to supply air to the cathode of the fuel cell stack.
