<P>PROBLEM TO BE SOLVED: To provide a start control method for a fuel cell system that can prevent failures such as erroneous valve opening, etc. when power generation processing at the stop time of the fuel cell system is executed. <P>SOLUTION: In a case where a start instruction of a fuel cell system 10 is detected after power generation processing at the stop time of a fuel cell 20 is executed and power generation of a fuel cell 20 stops, when anode pressure Pa of the fuel cell 20 is a first threshold pressure or less, there is executed first start processing of starting supply of fuel gas from a fuel gas supply device 16 before supply of oxidant gas is started by an oxidant gas supply device 14, and then starting supply of the oxidant gas after a predetermined time elapses from the start time of the fuel gas. Therefore, the fuel cell system can be started without increasing the pressure difference (the pressure difference between electrodes) between the atmosphere pressure equal to the pressure at a cathode side and the pressure at an anode side (with the pressure difference between the electrodes reduced), and an erroneous valve opening of an air inlet valve 55 through which the anode and the cathode intercommunicate with each other at the outside of the fuel cell 20, etc. can be prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
