Abstract
There are provided a solid oxide fuel cell system made up of (a) a solid oxide fuel cell stack, (b) a preliminary reformer for removing hydrocarbons having two or more carbon atoms from a hydrocarbon fuel by converting the hydrocarbons having two or more carbon atoms into methane, hydrogen, and carbon monoxide, and (c) an integrated heat exchanger for catalytic combustion for heating either air or fuel, or both the air and fuel, to be guided to the solid oxide fuel cell stack, by use of a combustion gas formed by combusting discharged fuel with the use of discharged air, wherein the component equipment described above are disposed in an adiabatic vessel and the integrated heat exchanger for catalytic combustion for use in the solid oxide fuel cell system.
