Abstract
An assembly for an electrochemical device is provided, including a gas diffusion layer and a sealing element produced on the gas diffusion layer. The sealing element includes an inner sealing region fixed to the gas diffusion layer and an outer sealing region connected to the gas diffusion layer via the inner sealing region. The assembly has minimal warpage without the temperature in the injection molding tool having to be lowered and/or a geometric pre-compensation of the warpage of the sealing element in the inner sealing region. The sealing element includes a relief region arranged between the inner and outer sealing regions and a) includes a relief opening extending through the sealing element and/or b) has a smallest height (h), which is smaller than both one fourth of the greatest height (H) of the inner sealing region and one fourth of the greatest height (H) of the outer sealing region.
