<P>PROBLEM TO BE SOLVED: To realize a pressure-adjusting control of a fuel gas supplied to a fuel cell by a simple system constitution. <P>SOLUTION: The fuel cell system (10) is provided with: a high-pressure regulator (A6) to adjust the pressure of the fuel gas supplied to the fuel cell (20) at a high pressure, a low-pressure regulator (A7) to adjust the pressure of the fuel cell at a low pressure; a reaction gas supply passage (31) to include branch/junction passages (31a, 31b) to connect these regulators (A6, A7) respectively in parallel; a shut-off valve (A2) to be connected to the high-pressure regulator (A6) in series on the downstream side than the branch/junction passages (31a, 31b) and on the upstream side than the junction (B2); and a control part (60) to adjust the supply pressure of the fuel gas by open-close controlling of the shut-off valve (A2). <P>COPYRIGHT: (C)2005,JPO&NCIPI |
