Open the CIPO recordAbstract From the Canadian patent
A cathode for a chlor-alkali cell is made by providing a steel cathode with a dense non-porous, electroless coating of nickel. Such a coating having a thickness of 1 to 15 microns is produced by immersing the steel cathode in a bath of suitable temperature the bath containing a suitable nickel salt water, a, complexing agent and a reducing agent. The cathode so coated hat a lower hydrogen overvoltage (by about 0.16 volt) than an uncoated steel cathode, and the effect persists through many months of use The invention thus makes it possible to achieve considerable savings of power in the electrolysis of brine in a chlor-alkali cell.
