<P>PROBLEM TO BE SOLVED: To provide a fuel cell unit which can control an increase of a passage pressure loss due to vapor condensation in gas and can control a deterioration of battery performance and humidifying performance. <P>SOLUTION: In the fuel cell unit 100, a fuel cell gas passage through which oxidized gas flows and a fuel cell offgas passage through which oxidized offgas flows in a fuel cell stack 1 are inclined downward or horizontal in a flowing direction respectively, and a humidifier gas passage through which the oxidized gas 7b flows and a humidifier offgas passage through which the oxidized offgas 6b flows inside a heat exchanging humidifier 2 are inclined downward or horizontal in a flowing direction respectively, and at least either an oxidized offgas connecting passage through which the oxidized offgas 6b flows or an oxidized gas connecting passage 25 through which the oxidized gas 7b flows, both provided on a connecting board 4, is inclined upward in a flowing direction. <P>COPYRIGHT: (C)2009,JPO&INPIT |
