<P>PROBLEM TO BE SOLVED: To provide a compact solid oxide fuel cell device having constitution generating steam for vaporizing liquid fuel before mixing with the liquid fuel and suppressing loss caused by heat radiation of combustion gas. <P>SOLUTION: A fuel cell device 100 forms a combustion chamber 150 housing reformers 170A, 170B reforming liquid fuel vaporized by mixing with steam to reformed gas and power generating devices 140A, 140B generating power from the reformed gas and air and heating the reformers 170A, 170B with combustion gas obtained by combustion of remaining reformed gas, by partitioning the inside, and is equipped with water passages 111B, 111C adjoined to the outer peripheral side of the combustion chamber 150 and generating steam from water by heat exchange with the combustion chamber 150; combustion gas passages 112A, 112B adjoined to the water passages 111B, 111C, and cooling the flowing combustion gas by heat exchange of water and steam flowing through the water passages 111B, 111C; and air passages 113C, 113D adjoined to the combustion gas passages 112A, 112B, and heating the flowing air by heat exchange with the combustion gas flowing through the combustion gas passages 112A, 112B. <P>COPYRIGHT: (C)2009,JPO&INPIT |
