Abstract
Official abstract text for this publication.
A fuel cell system includes a desulfurizer that removes a sulfur compound in a raw material, a fuel cell unit that performs electric-power generation using fuel obtained by reforming a raw material from which the sulfur compound is removed and electric-power generation air supplied, a combustion exhaust gas passage through which combustion exhaust gas generated by combusting fuel not utilized for the electric-power generation in the fuel cell unit is emitted, a combustion exhaust gas container that is connected to the combustion exhaust gas passage and accommodates the desulfurizer inside the combustion exhaust gas container, a purifier that removes carbon monoxide included in the combustion exhaust gas, and an air heat exchanger that performs heat exchange of the combustion exhaust gas and the electric-power generation air supplied to the fuel cell unit.
First claim
Opening claim text (preview).
What is claimed is: 1 . A fuel cell system comprising: a desulfurizer that removes a sulfur compound in a raw material; a fuel cell unit that performs electric-power generation using fuel obtained by reforming a raw material from which the sulfur compound is removed and electric-power generation air supplied; a combustion exhaust gas passage through which combustion exhaust gas generated by combusting fuel not utilized for the electric-power generation in the fuel cell unit is emitted; a combustion exhaust gas container that is connected to the combustion exhaust gas passage and accommodates the desulfurizer inside the combustion exhaust gas container; a purifier that removes carbon monoxide included in the combustion exhaust gas; and an air heat exchanger that performs heat exchange of the combustion exhaust gas and the electric-power generation air supplied to the fuel cell unit, the fuel cell unit being arranged in a first heat insulation space covered with a first heat insulator, the combustion exhaust gas container, the purifier, and the air heat exchanger being arranged in a second heat insulation space covered with a second heat insulator. 2 . The fuel cell system according to claim 1 , further comprising: a heater that heats at least one of the combustion exhaust gas container, the desulfurizer, and the purifier. 3 . The fuel cell system according to claim 1 , wherein the first heat insulation space is arranged so as to be adjacent to the second heat insulation space via the first heat insulator and the second heat insulator. 4 . The fuel cell system according to claim 1 , wherein the combustion exhaust gas container, the purifier and the air heat exchanger are arranged via at least one partition wall inside a single container covered with the second heat insulator. 5 . The fuel cell system according to claim 4 , wherein the partition wall between the air heat exchanger and the combustion exhaust gas container is provided with a heat-insulating material. 6 . The fuel cell system according to claim 1 , wherein the combustion exhaust gas flows through the combustion exhaust gas container, the purifier, and the air heat exchanger in this order. 7 . The fuel cell system according to claim 1 , further comprising: a main air heat exchanger provided in the fuel cell unit, wherein the air heat exchanger preheats electric-power generation air transferred to the main air heat exchanger. 8 . The fuel cell system according to claim 1 , further comprising: a lid that covers an opening provided in the purifier so that the opening is openable and closable.
