Abstract: The present disclosure relates to coatings. For example, some embodiments may include methods for producing a coating comprising: depositing a metallic matrix on a substrate by electrochemical deposition using a deposition bath including carbon comprising particles and oxide particles dispersed therein; wherein the carbon comprising particles are embedded into the metallic matrix and pores are distributed in the coating; wherein at least 80% of the pores have a pore diameter in a range from 3 to 30 ?m; wherein oxide particles are incorporated into and fixed in the pores during deposition and the oxide particles remain partially uncoated by the material of the metallic matrix.

Abstract: 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.
