<P>PROBLEM TO BE SOLVED: To provide a small and high-output fuel cell stack structure allowing series connection and parallel connection of unit cells to be selected, that is, capable of responding to both a high-voltage specification and a large-current specification. <P>SOLUTION: This fuel cell stack structure is composed by stacking, by interposing collectors 8, a plurality of cell units U each formed by jointing, to each other, respective edges of two cell plates 1 each holding a unit cell 10 and having a fuel gas introduction hole 2a at a central part; fuel electrodes 11, 11 of the respective unit cells 10 are faced to each other by interposing a fuel gas passage 4 formed between both the cell plates 1, 1 of each cell unit U; and the respective fuel electrodes 11, 11 of the unit cells 10 facing each other are electrically connected to the cell plates 1 of the cell unit U. <P>COPYRIGHT: (C)2008,JPO&INPIT |
