To provide a fuel cell operating method capable of preventing freezing of a reaction gas passage, and minimizing energy necessary for drainage by draining water in a system only when it is necessary.
In the operating method for a fuel cell 1, gaseous hydrogen and air are supplied as reaction gases to each reaction gas passage 5 and 6, and power generation is carried out by electrochemical reaction. It is characterized by that water in the reaction gas passages 5 and 6 are drained and operation of the fuel cell 1 is stopped by cutting off electric power supply from the fuel cell 1, detecting an outside air temperature, and supplying the reaction gases to the reaction gas passages 5 and 6 in response to the outside air temperature.
