PLATE, PLATE ASSEMBLY AND ELECTROCHEMICAL CELL STACK

摘要

Plate, more particularly a separator plate, provided with fluid channels which are designed as grooves. These fluid channels open out into continuous inlet or outlet openings. In the vicinity of the location where they open into the inlet or outlet, there is a cover for the groove or grooves, in order to provide a sealing surface with an adjoining part of a fuel cell stack. According to the invention, this cover consists of the same material as the plate in question. On the "undesirable", this cover is designed as a recess. If appropriate, a further opening may be present between the recess and the end of the grooves.
