SOLID OXIDE FUEL CELL APPARATUS

摘要

PROBLEM TO BE SOLVED: To suppress deterioration of the reforming performance due to temperature drop of gas supplied to a reformer from an evaporator, in a solid oxide fuel cell apparatus in which the evaporator is provided outside a module case.SOLUTION: A solid oxide fuel cell apparatus 1 comprises: a module case 8 for housing a plurality of fuel cell units 16; an adiabatic material 7 covering around the module case 8; a reformer 20 for generating fuel gas by reforming raw fuel gas by moisture vapor; a combustion chamber 18 for heating the reformer 20 by combusting the fuel gas; an exchanger 23 for exchanging heat between the oxidant gas and the exhaust gas; an evaporator 25 for generating moisture vapor by exchanging heat between water and the exhaust gas; and a mixed gas supplying pipe 62 extending across the adiabatic material 7 and the module case 8 in vertical direction and supplying the vapor from the evaporator 23 to the reformer 20, and the evaporator 25 is arranged on a position above the module case 8 corresponding to an inlet side of the reformer 20.SELECTED DRAWING: Figure 2
