Abstract:

Hydrogen overvoltage on Bi polycrystalline and single crystal cathodes, oriented following the 100, 110 and 111 planes, was investigated in HC104 solutions in a current density range to 100 ampsq m at 25 and 55 C. The Tafel law holds true at high current density values the parameters being different for the different electrodes. In the lower current density range, the behavior, as revealed by oscillographic recordings, is anomalous and different from that observed with other metals. Author
