ELECTROLYZER WITH FILAMENT SPACING FOR DIAPHRAGM AND ELECTRODES

摘要

ELECTROLYZER WITH FILAMENT SPACING FOR DIAPHRAGM AND ELECTRODES An electrolyzer for alkaline electrolysis of water has a diaphragm-electrode sandwich arrangement wherein a predetermined narrow spacing to provide a minimum distance" is maintained between the diaphragm surface and the superjacent electrode. The spacing is provided by a single layer of a filament of predetermined thickness disposed in an array. the filament is strung in a plurality of lengths disposed in a common plane so that the thickness of the spacing is the same as the thickness of the single layer which is equal to the filament thickness of the is secured by a retaining wire which engages a groove provided in a cell frame of the electrolyzer. The filament is made of plastic material, preferably having a thickness of 50 to 500 microns, which can withstand electrolysis conditions. An apparatus and method for stringing the filament to provide the array are also described.
