Gaz Diffusion Layers from functional carbon materials for fuel cells used in energy installations

Gas Diffusion Layers (GDL) for fuel cells are two-dimensional carbon materials designed to obtain a smaller thickness, greater bending stiffness, lower residual deformation and lower compressibility compared to analogs. To produce it, functional carbon materials were used: activated carbon of own production, from vegetable raw materials, acetylene black and single-walled Tuball nanotubes. Dependence on the amount of binder is shown, as are the properties of electrodes made by calendering. The resistance of the rolled electrodes is much lower than that of the sputtered electrodes. There are proposed 4 variants of electrodes, which can be used in fuel cells and are used in power energy installations.
