Claim 2:
3. The fuel cell system according to claim 1, further comprising:
a power generation quantity detection unit configured to detect an accumulated power generation quantity from a reference timing point;
a generated water storage tank provided in the gas circulation passage and configured to store the generated water flowing out of the cathode-side internal passage; and
a generated water quantity detection device configured to detect a flow rate of the generated water stored in the generated water storage tank,
wherein the control device switches a flow direction of oxygen gas by the gas circulation device when a difference between a quantity of the generated water estimated from an accumulated power generation quantity detected by the power generation quantity detection unit and the generated water quantity detected by the generated water quantity detection device has become a threshold or more.
