Abstract
In a case that activation is implemented on a fuel cell, a variable voltage is applied to a membrane electrode assembly while a first gas is supplied to an anode and a second gas is supplied to a cathode. Thereafter, while a constant voltage is applied to the membrane electrode assembly, liquid water is generated at the anode or the cathode. Alternatively, the membrane electrode assembly is made to generate electricity. During the generation of electricity, liquid water is generated at the anode or the cathode.
