<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack structure which can select serial and parallel connections of single cells, that is, meet both of high voltage and high current specifications with small size and high output. <P>SOLUTION: The fuel cell stack structure comprises a stack of many cell plates 1 formed in a manner of bonding support materials 2 and 3 to the inner and outer circumferential portions of an annular single cell 10, respectively. A space between the cell plates 1, 1 overlapping with each other is formed as a gas flow path 4, and many cell plates 1 are arranged with fuel electrodes 11, 11 of the single cell 10 in opposition to each other. The inner peripheral side support material 2 and the outer peripheral side support material 3 of the cell plate 1 is electrically disconnected, and the inner peripheral side support material 2 and the outer peripheral side support material 3 of the cell plate 1 are served as connection terminals for the single cell 10. <P>COPYRIGHT: (C)2008,JPO&INPIT |
