Title: Oxidatively stable microlayers of gas diffusion layers

Abstract

The present invention is a microlayer for use with an electrically conductive porous substrate of a gas diffusion layer. The microlayer includes carbon particles and a polymeric composition of first highly-fluorinated polymers that are non-melt processable and second highly-fluorinated polymers that are melt processable.
