<P>PROBLEM TO BE SOLVED: To suppress, to a minimum, pressure detection errors near an opening and closing valve in a fuel cell system in which the opening and closing valve such as an injector is arranged in a fuel supply passage. <P>SOLUTION: The fuel cell system 1 includes a fuel cell 10, a fuel supply passage 31 for supplying a fuel gas supplied from a fuel supply source 30 to the fuel cell 10, an opening and closing valve 35 which adjusts the gas state on the upstream side of the fuel supply passage 31 and supplies the gas to the downstream side, and a control means 4 which drive-controls the opening and closing valve 35 with a prescribed drive period. The control means 4 establishes the upper limit value of a duty ratio in each drive period of the opening and closing valve 35. <P>COPYRIGHT: (C)2009,JPO&INPIT |
