<P>PROBLEM TO BE SOLVED: To provide a fuel cell system in which a fuel cell device is allowed to be brought into a non-operation state, in which wasteful energy consumption due to successive operations of the fuel cell device can be suppressed, long lifetimes of various auxiliary equipment are obtained, and a cell periphery can be maintained in a reducing atmosphere. <P>SOLUTION: This system is provided with a plurality of fuel cell devices (Ua, Ub), and in each of the plurality of fuel cell devices (Ua, Ub), branch lines (E3, E5a, E8a, E10a: E3, E5b, E8b, E10b) branched from exhaust gas lines (E1a, E1b) through which exhaust gas from fuel poles (12a, 12b) flows are communicated with a piping system (bypass circuit Eab) to join the exhaust gas to fuel gas supply lines (F3a, F3b) of the other fuel cell devices. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
