TEXTURED SEPARATOR PLATE AND METHOD OF MAKING

摘要

The present invention comprises a textured separator plate having specific desirable surface characteristics and method of manufacture of said plate. The separator plate in one embodiment is fashioned from steel which is textured by cold working, for example, by a laser-matte rolling process. Preferably, the surface texture is a repeatable bi-dimensional pattern exhibiting a surface profile which is plateau-like in appearance, the texture comprising a regular pattern of curvilinear recesses defining island-like features.
