A TECHNIQUE FOR IN-SITU ANODE ACTIVATION BY A CATHODE IN AN ALKALINE WATER ELECTROLYTIC CELL

摘要

An electrolytic cell for alkaline water electrolysis with in-situ anode activation comprising: an anode; a cathode wherein at least a part of a surface of the cathode comprises an electrically conducting stable material and an anode catalytic material adapted to be released from the surface of the cathode in alkaline water and be deposited at a surface of the anode when an electric voltage is applied across the anode and the cathode; and a diaphragm separating the anode and the cathode, wherein the diaphragm is gas tight and is permeable to the anode catalytic material.
