<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack capable of being suitable for on-board application by effectively miniaturizing and smoothly and surely discharging water introduced in an interconnecting hole. <P>SOLUTION: An outlet-side oxidizer gas interconnecting hole 38b is arranged on the fuel cell stack 10, first and second oxidizer gas passage grooves 42, 44 are arranged on the surface 14a of a first separator 14 in the gravity direction so as to meander in the horizontal direction, and the second oxidizer gas passage grooves 44 is connected with the outlet-side oxidizer gas interconnecting hole 38b via a second oxidizer gas connection passage 48. A porous water suction tube 86 for discharging water to the outside of the fuel cell stack 10 by a capillary phenomenon and differential pressure of air is arranged on the outlet-side oxidizer gas interconnecting hole 38b. <P>COPYRIGHT: (C)2009,JPO&INPIT |
