<P>PROBLEM TO BE SOLVED: To solve problems with conventional fuel cells that pressure loss becomes large at an inlet part of a gas passage and that distribution of a reaction gas in the gas passage becomes uneven. <P>SOLUTION: A unit cell 1, a separator 2 forming a closed space between the unit cell 1 and itself, and a gas guide member 3 interposed between the unit cell 1 and the separator 2 are provided. The gas guide member 3 comprises: an introduction passage 3A which allows communication between gas introduction holes (HA) and the closed space; a discharge passage 3B which allows communication between gas discharge holes HB and the closed space; and a partitioning part 3C which forms a gas passage extending from the introduction passage 3A to the discharge passage 3B in the closed space. By providing a fuel cell C in which the introduction passage 3A has a minimum cross-sectional area larger than a minimum cross-sectional area of the discharge passage 3B, pressure loss at an inlet part A of the gas passage becomes smaller and distribution of a reaction gas in the gas passage becomes even. <P>COPYRIGHT: (C)2013,JPO&INPIT |
