<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack that, with a simple and compact configuration, ensures desired clamp loads to be applied to different portions in a solid oxide fuel cell, and prevents heat dissipation so as to allow high-efficiency power generation. <P>SOLUTION: A fuel cell stack 10 includes: a bottom end plate 38 on which a laminate 36 is placed; a load plate 46 that applies load to the laminate 36 along a laminate direction; and a fuel cell holding section 44 that is arranged between the load plate 46 and the laminate 36 and has a composite layer of alumina fiber and vermiculite. The fuel cell holding section 44 has: a first holding portion 44a that corresponds to a membrane electrode assembly 20 and applies load to sandwiching portions 35 in the laminate direction; and a second holding portion 44b that applies load to reactant gas supply portions 37 in the laminate direction. The first holding portion 44a is set to be less dense than the second holding portion 44b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
