<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of reducing noise of an air compressor of a fuel cell and improving starting performance at next time. <P>SOLUTION: The liquid droplet in an oxidizer gas passage and a fuel gas passage is removed divided in time so that the flow-rate in the oxidizer gas passage and the flow-rate in the fuel gas passage may not be large at the same time after turning off of an ignition switch (points of time t12-t14), thereby drive of an air compressor can be suppressed and noise can be reduced. Thereafter, drying of an electrolyte membrane is promoted by the oxidizer gas (points of time t14-t15), thereby starting performance at next time can be improved. <P>COPYRIGHT: (C)2007,JPO&INPIT |
