<P>PROBLEM TO BE SOLVED: To suppress fuel gas ripple generated by driving of an injector, without enlarging a fuel cell system. <P>SOLUTION: The fuel cell system 1 includes a supply flow channel 31 supplying fuel gas from a fuel gas supply source to a fuel cell, a regulator 34 fitted at the supply flow channel 31 and regulating pressure of the fuel gas, and an injector 35 fitted at a downstream side of the regulator 34 of the supply flow channel 31 and supplying fuel gas to a fuel cell side by regulating supply conditions of the fuel gas. The regulator 34 is of a diaphragm type and has a pressure regulating chamber S1 for the fuel gas to flow in, a back pressure chamber S2, and a diaphragm 60 housed in a case 50. A gas flowing part 35a of the injector 35 is connected to a position facing to the diaphragm 60 of the case 50 at a pressure regulating chamber S1 side of the regulator 34. <P>COPYRIGHT: (C)2009,JPO&INPIT |
