摘要：

The electrocatalytical properties of the lanthanum phosphate-bonded composite nickel-rhodium electrodes for the hydrogen and oxygen evolution reactions were investigated in 1M alkaline solution at 25-degrees-C. The electrodes were prepared from chemical deposition of rhodium on nickel particles and subsequent polymerization of Ni/Rh powder with lanthanum phosphate. The influence of the rhodium content and other experimental conditions during the electrode preparation were considered in relation with the electrocatalytical activity. The ac impedance and steady-state polarization methods were used to investigate the mechanism and kinetics of the hydrogen evolution reaction.
