<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack which facilitates fuel cell positioning and, for example, ensures high power generation performance and good gas diffusion performance, a reactor stack and their fabrication methods. <P>SOLUTION: A fuel cell stack 1 has a fuel cell layer 5 in which a plurality of fuel cells 3 are arranged in parallel, each having a cylindrical inner electrode 11 and a solid electrolyte layer 13 formed on its outer surface, wherein the fuel cell layer 5 is sandwiched with a conductive plate 9 composed of porous conductive ceramics in its thickness direction. In addition, each fuel cell 3 has an outer electrode 7 between the solid electrolyte layer 13 and conductive plate 9, and a gas transmission coefficient in the conductive plate 9 is 5×10<SP>-5</SP>mlcmcm<SP>-2</SP>sec<SP>-1</SP>Pa<SP>-1</SP>or more. <P>COPYRIGHT: (C)2008,JPO&INPIT |
