METHOD OF STABILISING ELECTRODES COATED WITH MIXED OXIDE ELECTROCATALYSTS DURING USE IN ELECTROCHEMICAL CELLS |
摘要 |
The invention relates to an electrochemical cell with an electrode having deposited thereon an electrocatalyst which is a mixed oxide of nickel-molybdenum, nickel-tungsten, cobalt-molybdenum or cobalt-tungsten and containing an aqueous alkaline electrolyte comprising an aqueous solution of a molybdenum, vanadium or tungsten compound. The electrodes are preferably prepared by alternately coating an electrode core with a compound of nickel or cobalt, and with a compound of molybdenum or tungsten, said compounds being capable of thermal decomposition to the corresponding oxides, heating the coated core at an elevated temperature to form a layer of the mixed oxides on the core and finally curing the core with the mixed oxide layer thereon in a reducing atmosphere at a temperature between 350.degree.C and 600.degree.C. |
