Experimental data are presented on wear and destruction of cathode materials (steel, pig-iron, zinc, copper) in the course of long-term electrolytic hydrogen enrichment, redistribution of doping elements in steel and in pig-iron, appearance of dendrites on the cathode edges and puts on the specimen surface. The results are explained by hydrogen «pumping» into the metal structure and formation of metal hydride. Chemical analysis of the evolved gas shows appearance of hydrocarbons (from methane to hexane) in the course of hydrogen enrichment of carbon-containing metals.
