Solid polymer fuel battery activation method

Abstract

A solid polymer fuel battery activation method is an activation method of a solid polymer fuel battery that comprises an anode electrode, a cathode electrode, and a solid polymer membrane arranged between the anode electrode and the cathode electrode, the method including: a CV operation step in which, in a state where nitrogen is supplied to the cathode electrode and hydrogen is supplied to the anode electrode, a voltage that varies within a predetermined width is scanned between the cathode electrode and the anode electrode while setting the cathode electrode to be positive by an external electric power source, wherein in the CV operation step, an activity state of a catalyst contained in the cathode electrode is measured from a measurement value of a cyclic voltammogram, and activation completion of the solid polymer fuel battery is determined from a measurement value indicating the activity state of the catalyst.
