<P>PROBLEM TO BE SOLVED: To efficiently remove residual water in a fuel cell stack 30 while suppressing deterioration of a secondary battery 44 in a fuel cell system 28. <P>SOLUTION: An air compressor 32 to supply air to the fuel cell stack 30, the secondary battery 44 to supply electric power to the air compressor 32, a temperature sensor 46 to detect a temperature of the secondary battery 44, and a control part 48 are installed. The control part 48 has a charge amount monitoring means 50 to detect a charge amount of the secondary battery 44, and has a scavenging air supply controlling means to control an operation state of the air compressor 32. The scavenging air supply controlling means decides the scavenging state including a supply flow amount of the air by the residual water amount in the fuel cell stack 30 estimated by a residual water estimating means and by the detected temperature and the charge amount, and controls the operation state including the supply flow rate of the air compressor 32. <P>COPYRIGHT: (C)2008,JPO&INPIT |
