Electrochemical percolation type cell, its uses in chlor-alkaline and fuel cell process and manufacturing process of a gas diffusion electrode

摘要

The present invention relates to a gas diffusion electrode for chlor-alkaline electrolysis cells integrated into a suitable porous plastic percolator. vertically crossed by a flow of spilled electrolyte. The electrode comprises a silver and / or nickel based catalytic composition mixed in a polymeric binder directly supported on the percolator without any overlapping crosslinked metal collecting current.
