<P>PROBLEM TO BE SOLVED: To provide an operation method of an indirect interior reforming type SOFC system capable of preventing lack of heating of a reformer at the time of power generation and standby of power generation. <P>SOLUTION: The operation method of the indirect interior reforming type SOFC system at the time of power generation or standby of power generation, includes a reformer equipped with a reforming catalyst layer, an SOFC, an electric heater heating the reforming catalyst layer and containing a plurality of resistors capable of conducting independently, a plurality of temperature detecting means for detecting a temperature of a plurality of sites having a different phase of the reforming catalyst layer respectively, and a heater control means capable of selectively conducting an arbitrary site and the number of resistors among the plurality of the resistors based on the temperature detected by the temperature detecting means, and the reformer is arranged at a position capable of receiving heat from the SOFC. Furthermore, the operation method includes a heat assist process compensating lack of heat of the reforming catalyst layer by conducting at least one or more resistors selected from the plurality of resistors, with the use of the heater control means, and based on the temperature detected by the temperature detecting means. <P>COPYRIGHT: (C)2011,JPO&INPIT |
