<P>PROBLEM TO BE SOLVED: To provide a fuel cell system with its structure simplified, its energy efficiency improved, and capable of stably driving its fuel cell. <P>SOLUTION: The fuel cell system 1 includes a reformer 2 for producing hydrogen-containing reformed gas G<SB>H</SB>containing hydrogen and CO, and a fuel cell 3 for generating power using the hydrogen-containing reformed gas G<SB>H</SB>. The fuel cell 3 has an anode flow channel 31 supplied with the hydrogen-containing reformed gas G<SB>H</SB>, a cathode flow channel 32 supplied with oxygen-containing gas G<SB>O</SB>, and an electrolyte body 33 arranged between them. The electrolyte body 33 is made by laminating a hydrogen-separating metal layer for permeating hydrogen in the hydrogen-containing reformed gas G<SB>H</SB>, and a proton conductive layer made of ceramics for letting the permeated hydrogen reach the cathode flow channel 32 in a proton state. Furthermore, the fuel cell system 1 is provided with a CO removing device 5 for removing CO in the hydrogen-containing reformed gas G<SB>H</SB>. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
