PROBLEM TO BE SOLVED: To provide a fuel cell stack for lubricating and completely exhausting water introduced into a communicating hole with effectively compacting size to be suitable for mounting on a vehicle. SOLUTION: An fuel cell stack 10 is provided with an outlet side oxidizer gas-communicating hole 38b, a plane 14a of first separator 14 is provided with an oxidizer gas flowing channel grooves 42, 44, with which the grooves face with each other in the gravity direction while meandering in the horizontal direction, a second oxidizer gas flowing channel groove 44 is communicated with the outlet side oxidizer gas communicating hole 38b via an oxidizer gas connecting channel 48. The outlet side oxidizer gas communicating hole 38b is provided with a porous of absorption tube 86 for exhausting water into an outside of the fuel cell stack 10 by capillary phenomenon and difference in the atmospheric pressure. |
