Abstract

A method of forming a gas diffusion layer includes causing, at least in part, a stack of layers to be arranged between compressing surfaces of a press, the stack of layers including a plurality of gas diffusion layers. The method also includes causing, at least in part, the press to apply one or more compression cycles to the stack of layers to reduce a combined, uncompressed thickness of the plurality of gas diffusion layers between about 2% and about 30%.
