GKD offers specially adapted wire meshes for virtually all fuel cell designs. Their porosity and conductivity, as well as their subsequent assembly, open up many options for optimum adaptation to the individual design. For example, metal meshes produced from nickel alloys are used as power distributors on the anode side (H2 electrode) and contact media.

The post-processing options of the meshes used, such as high-precision thickness calibration and thermal treatment to ensure maximum freedom from oil and also the requisite formability, allow optimum matching to the cell manufacturing process. Thanks to their high porosity, GKD mesh solutions based on volumetric meshes in particular offer outstanding properties for use in gas diffusion layers or spacer layers in flowfield applications.
