NEGATIVE ELECTRODE STRUCTURE FOR ELECTRODE AND ELECTROLYSIS TANK USING SAME

摘要

Provided is an electrode structure capable of maintaining the distance between an electrode and electrode collector at a substantially fixed value. Specifically provided is a negative electrode structure for an electrode capable of controlling deterioration in an active negative electrode even when reverse current flows when the operation of an electrolysis tank is stopped. The negative electrode structure for an electrode accommodates a metal elastic cushion material (1) between an active electrode (2) and a negative electrode collector (3) by compression. At least the surface layer of the negative electrode collector (3) consumes a greater oxidation current per unit surface area than the active negative electrode. The electrolysis tank is compartmentalized into a positive electrode chamber accommodating a positive electrode and a negative electrode chamber accommodating the negative electrode by an ion exchange membrane. The negative electrode structure for an electrode described above is used for the negative electrode.
