ABSTRACT:
By using a fuel cell having a membrane electrode assembly having and electrolyte membrane100formed by a polymer electrolyte membrane, and an anode101and a cathode102carrying a catalytic metal and sandwiching electrolyte membrane100. The anode101and the cathode102are in electrical connection, and an activation treatment is carried out for opening an active site of catalytic metal of the cathode102. This provides an activation method of a polymer electrolyte fuel cell which is advantageous to activation and raises cell voltage.
