摘要： A fuel cell is provided that is reduced in both size and weight while securing a sealed state of respective flow passages by respective sealing members between separators and an electrode assembly. In this fuel cell, there are provided in each of the separators communication ports for reaction gases and cooling medium that are provided outward from gas sealing members, and communication paths that detour around the gas sealing members in the thickness direction of the separators and connect the reaction gas communication ports with gas flow passages. A cooling surface sealing member that seals off the cooling medium flow passage from the reaction gas communication ports is placed at a position shifted from the communication paths towards the communication holes. In addition, convex portions are provided between the reaction gas flow passages and the communications ports of one separator, while concave portions that receive the convex portion are provided in the other separator, and convex portions are formed behind the concave portions.

摘要： A fuel cell stack (10) includes a first sub-stack (12), a second sub-stack (14), and a third sub-stack (16) disposed in the flow direction of an oxidizing gas. An intermediate plate (18a) is interposed between the first and second sub-stacks (12, 14), and an intermediate plate (18b) is interposed between the second and third sub-stacks (14, 16). In this fuel stack (10), the flow of an oxidizing gas is set such that the oxidizing gas flows in series in the direction from the first sub-stack (12) to the third sub-stack (16). Between the sub-stacks additional oxidizing gas supplies (70,74) are provided through which oxidizing gas of lower humidity than the humidity of the oxidizing gas entering the first sub-stack is supplied. This arrangement allows an efficient management of the humidity water content of the oxidizing gas with sufficient moisturizing of the solid polymer membrane whilst avoiding excessive condensation of water vapour within the stack.
