Abstract
A first supply port, a first discharge port, a second supply port, and a second discharge port are formed in a fuel cell. At a time when the fuel cell is activated, a gas supplying step, and a gas flow direction switching step are performed. In the gas supplying step, a first gas is introduced into the fuel cell through the first supply port or the first discharge port, and a second gas is introduced into the fuel cell through the second supply port or the second discharge port. In the gas flow direction switching step, the flow direction of the first gas or the flow direction of the second gas is switched to an opposite direction.
