<P>PROBLEM TO BE SOLVED: To prevent powder from choking flow channels of a fuel cell system or a hydrogen manufacturing device and from flowing into hydrogen containing gas or fluid supplied to a fuel cell. <P>SOLUTION: The fuel cell system is provided with filters of a plurality of systems arrayed in parallel at an upstream of the fuel cell and a flow-channel switching means for switching between the filters of a part of the systems and those of the rest of the plurality of systems. The hydrogen manufacturing device manufacturing hydrogen-containing gas containing hydrogen by reforming a material for hydrogen manufacture is provided with the filters of the plurality of systems arrayed in parallel, and the flow-channel switching means for switching between the filters of a part of the systems and those of the rest of the plurality of systems. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
