Summary:An operation method of a fuel cell system includes the step of determining whether or not performance recovery control of a fuel cell stack should be started. This operation method includes the step of, if it is determined that the performance recovery control should be started, supplying water content to a membrane electrode assembly by a water content adjusting device, while maintaining power generation voltage of the fuel cell stack at 0.3 V or lower in a state where an oxygen-containing gas is circulated through a closed circulation channel.
