The requirements which must be met by electrocatalysts in electrochemi
cal devices were discussed: high activity, high stability, and low cos
t. The special features of catalytically active anodes and cathodes, e
lectrodes of fuel cells and primary batteries, electrolyzers for the p
roduction of hydrogen, chlorine, oxygen, oxygen compounds of chlorine,
peroxides, and metals, as well of electrochemical equipment for the t
reatment of natural waters and effluents were discussed.
