<P>PROBLEM TO BE SOLVED: To provide a cell stack of a fuel cell capable of suppressing the occurrence of breakage such as cracks in a unit cell in the cell stack formed by arranging a plurality of unit cells in a line. <P>SOLUTION: In the cell stack 1 of the fuel cell formed by arranging a plurality of unit cells 2 in a line, joining ends of them in a state buried in a sealing material 13, putting each current collecting member 3a between adjoined unit cells 2, and joining each member to the unit cells 2, stress applied to the unit cells 2 can be relaxed by positioning the end on the sealing material 13 side of the current collecting member 3a arranged on one end side in the arranging direction of the unit cells 2 on the surface of the sealing material 13. Thereby, the occurrence of breakage such as cracks in the unit cells 2 can be suppressed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
