wherein the fuel cell system comprises:
a fuel cell,
a fuel gas system for supplying fuel gas to the fuel cell,
a potential sensor, and
a controller;
wherein the fuel gas system comprises a fuel gas supplier;
wherein the controller determines whether or not a potential of the fuel cell measured by the potential sensor, is a reversal potential; and
wherein, when the controller determines that the potential of the fuel cell is a reversal potential, the controller increases a fuel gas supply from the fuel gas supplier to the fuel cell.
