1. A method comprising:
causing, at least in part, a stack of layers to be arranged between compressing surfaces of a press, the stack of layers comprising a plurality of gas diffusion layers stacked directly upon one another; and
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 by about 2% to about 30%.
