Brennstoffzellenstapel

摘要

A first separator has its surface which is designed to have a rectangular configuration. A fuel gas flow passage for making communication between a fuel gas inlet and a fuel gas outlet is provided on the surface. The fuel gas flow passage is designed to have a meandering configuration so that it extends in a long side direction and it turns back on a short side to allow a fuel gas to flow in the direction of the gravity. Accordingly, it is possible to effectively shorten a size in the height direction, and it is possible to obtain desired power generation performance with a simple structure.
