Abstract
A fuel cell system includes a fuel cell stack, a circulation circuit, a gas liquid separator section, a purge channel, a purge valve and an ECU. In a method of operating the fuel cell system at low temperature, after start-up of the fuel cell system, the ECU performs a freezing determination processing step of determining freezing or non-freezing of the gas liquid separator, and in the case where freezing of the gas liquid separator is determined in the freezing determination step, the ECU performs a freezing confirmation processing step of immediately opening the purge valve for predetermined time.
