<P>PROBLEM TO BE SOLVED: To supply gas to a fuel cell without impairing reliability and economic efficiency. <P>SOLUTION: In the gas supply system 10, when the fuel cell 30 is started, a solenoid on-off valve 320 is opened to operate a pressure reducing part 300. When the solenoid on-off valve 320 is opened, hydrogen gas is supplied to the fuel cell 30 by a line from a hydrogen gas passage 210 via an auxiliary passage 310 and an orifice 330. When the operating time of the pressure reducing part 300 reaches a predetermined value, a control part 300 opens a solenoid on-off valve 220 in a secondary supply part 200 and supplies hydrogen gas to the fuel cell 30 from the hydrogen gas passage 210. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
