<P>PROBLEM TO BE SOLVED: To provide a system which eliminates the need for separate temperature rising equipment and assures easy start-up while preventing fuel slip as a system having the indirect internal modifying type SOFC (solid oxide fuel cell) for burning anode offgas in a module vessel, then heating the modifier or SOFC utilizing the resultant combustion heat, as well as to provide start-up and operation methods for such a system. <P>SOLUTION: The indirect internal modifying type SOFC system includes a modifier having a modifying catalyst layer capable of modifying vaporized liquid fuel into partially-oxidized and vapor gas, an SOFC for performing power generation using the modified gas obtained by the modifier, and a vessel for housing the modifier and SOFC, wherein the modifier is located at a position for receiving heat radiation from SOFC. Further, such a system comprises an indirect internal modifying type SOFC which can burn the anode offgas discharged from an anode of the SOFC in the vessel, a liquid fuel vaporization supply means which vaporizes the liquid fuel and supplies it to the modifier, and a gas fuel supply means for supplying the gas fuel to the modifier. <P>COPYRIGHT: (C)2008,JPO&INPIT |
