摘要:
The invention relates to an assembly of a porous metallic gas diffusion substrate and a polymeric separator membrane for use in an alkaline electrolyser or alkaline fuel cell. The polymeric separator membrane of the assembly comprises inorganic hydrophilic particulates dispersed in an organic polymeric binder. The polymeric separator membrane is gas tight when filled with electrolyte. The polymeric separator membrane is penetrating into at least a top portion of the porous metallic gas diffusion substrate. Also disclosed is a method to produce such an assembly via coating a paste on a porous metallic gas diffusion substrate.
