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%.
Claims22
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, the press being a hot press or a laminator;
- 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%, and a setpoint temperature of the compressing surfaces is between about 20° C. and about 80° C. during the one or more compression cycles.
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;
- 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%, wherein each of the one or more compression cycles comprises pressure being progressively applied up to a maximum pressure between about 100 psi and about 400 psi, and wherein each of the one or more compression cycles comprises the maximum pressure being applied for about 2 minutes to about 11 minutes.
