<P>PROBLEM TO BE SOLVED: To reduce uncomfortable feeling about acoustic feeling given to a user by noise caused by the supply of oxidization gas used for dilution. <P>SOLUTION: A fuel cell system 1 includes a fuel cell 10 having an anode and a cathode, a fuel-gas supply means 31 for supplying fuel gas to the anode, an oxidization-gas supply means 21 for supplying oxidization gas to the cathode, and a diluting means 40 for diluting fuel gas discharged from the anode by oxidization gas discharged from the cathode. The fuel cell system 1 is configured so that, when starting the replacement of fuel gas in the fuel cell system 1 with new fuel gas supplied from the fuel-gas supply means 31, a supply amount of oxidization gas supplied from the oxidization-gas supply means 21 is increased compared with the case that, during normal operation, and the supply amount is gradually reduced by the finish of the replacement of fuel gas. <P>COPYRIGHT: (C)2009,JPO&INPIT |
