METAL STACK FOR FUEL CELLS OR ELECTROLYSERS

摘要

A stack, to be used in a fuel cell or electrolyser, comprises a collector layer (31), at least one diffusion layer (32a, 32b) and at least one anchoring layer (33a, 33b). The collector layer being a metal foil or metal plate or foamed metal sheet, the diffusion layer being a metal mesh or expanded metal sheet. An anchoring layer having a thickness of less than 0.5mm and comprising metal fibers, is sintered between the collector layer and the diffusion layer.
