Lahive & Cockfield, LLP
Fuel cell
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.
