<P>PROBLEM TO BE SOLVED: To provide a gas passage structure and an operation control device as well as an operation control method for a fuel cell system which are suitable for the hydrogen-on type fuel cell system and can quickly restart. <P>SOLUTION: The gas passage structure for a fuel cell system comprises a cathode inlet valve 41 arranged on a cathode introduction passage 21a at an upstream side of a fuel cell stack 10 and controlling a flow of a cathode gas introduced to the fuel cell stack 10, a cathode outlet valve 42 arranged on a cathode discharge passage 21b at a downstream side of the fuel cell stack 10 and controlling a flow of the cathode gas discharged from the fuel cell stack 10, and a bypass passage 43 branched from the cathode discharge passage 21b at the upstream rather than the cathode outlet valve 42 and detouring the cathode outlet valve 42. <P>COPYRIGHT: (C)2009,JPO&INPIT |
