ABSTRACT:
In the continuous manufacture of plastic-cohered gas diffusion electrodes, and particularly air electrodes, in the form of thin foils, a dry mixture of PTFE and active carbon powder is subjected, during the mixing process in a paddle mixer, to the additional intensive influence of rapidly rotating cutting knives. The degree of subdivision and homogeneity of the dry mixture is thereby enhanced to such a degree that, in the finished electrode tape, the mass does not exhibit nonuniform thickening.
