<P>PROBLEM TO BE SOLVED: To provide a cell stack device, a fuel cell module, and a fuel cell device capable of suppressing deterioration of the end portion current collecting member and improved in long-period reliability. <P>SOLUTION: The cell stack device 1 includes: a cell stack 2 which is equipped with a fuel gas flow passage 13 inside, and by aligning a plurality of fuel battery cells 3 via a current collecting member 4 in an upright state, a fuel gas unused for power generation is combusted; a conductive member 5 arranged to pinch the cell stack 2 from both ends; and a manifold 7 to fix one end portion side of the fuel battery cells 3 and in order to supply the fuel gas. Since the conductive member 5 has a plurality of current extraction portions 6 by having a spacing in the longitudinal direction of the fuel battery cells 3, current concentration in the current extraction portions 6 can be suppressed, and the cell stack device 1, a fuel cell module 20, and the fuel cell device 25 are improved in long-period reliability. <P>COPYRIGHT: (C)2011,JPO&INPIT |
