<P>PROBLEM TO BE SOLVED: To prevent a hydrogen-permeable metal layer from being embrittled by hydrogen remaining in the metal layer, in a device which uses hydrogen in a hydrogen-containing gas by causing the hydrogen to permeate the metal layer. <P>SOLUTION: A hydrogen-permeable metal section composed of a hydrogen-permeable metal layer 22 and an electrolyte layer 21 is joined to a supporting area 24a of a supporting section 24 at a second plane of a supported area surface S. A stacking area 24b of the supporting section 24 is kept in contact with a gas separator 27. On a first plane of the hydrogen-permeable metal layer 22, an anode 23 is installed, and on the anode 23, an in-single-cell fuel gas channel 30 is formed. On a second plane of the hydrogen-permeable metal layer, the electrolyte layer 21 and a cathode 25 are formed one after another, and on the cathode 25, an in-single-cell oxidation gas channel 32 is formed. In the in-single-cell fuel gas channel 30, a purge gas can be supplied. A first plane of the whole of the supported area S is exposed to a gas passing through the in-single-cell fuel gas channel 30. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
