Improved in situ reduction of the passivating oxide layer on titanium components of the anode of a pem electrolyzer

摘要

By means of a method comprising the polarization of the anode at a suitable potential and supply of the anode with a reducing medium, the oxide layers of titan of the anodes of pem electrolysis cells be reduced. This reduces, on the one hand, the necessity of passivating coatings of such titan, on the other hand, a reduction of the ohmic contact resistances increasing the service life of the achieved titanium anode structures.
