Abstract
A fuel cell system in which a low open circuit voltage (OCV) is maintained in a start-up mode and in a shut-down mode, and a method of operating the same, the method including: supplying an anode off-gas and air to the cathode in an open circuit voltage state in a start-up mode and cutting off supply of the fuel gas to the cathode in a normal operating mode; and supplying the fuel gas and air to the cathode in a shut-down mode, and if a load is cut off, purging the cathode and the anode in the OCV state.
