<P>PROBLEM TO BE SOLVED: To provide an operation method in which a consumption of purging inert gas when it is stored during shutdown of power generation can be minimized and moreover a performance deterioration of a reforming catalyst can be avoided. <P>SOLUTION: A raw fuel supply shutdown valve 1 and a steam supply shutdown valve 10 and an exhaust valve 13 are shifted to a closed status, and inert gas purge valves 11, 12, 15 are shifted to an open status, and purging inert gas is sent from an air electrode 5b, then from a gas-liquid separation unit 8, then from a desulfurizer unit 2, a fuel reforming unit 3 and a CO converter 4, to a fuel electrode 5a, and purges all above units one by one, and is exhausted after being used for heating the fuel reforming unit 3 by a heater 7. <P>COPYRIGHT: (C)2009,JPO&INPIT |
