摘要：

The electrochemical formation of nickel hydride in alkaline solutions is discussed and compared with known results in acid solutions and investigations in high pressure electrolysis. It is supposed that probably surface or subsurface hydrides are formed in alkaline solutions, instead of the bulk, three-dimensional hydride. The importance of electrochemical investigations in this respect is stressed, but a warning is expressed for overinterpretations of the equivalence between the overvoltage and the effective thermodynamic activity on the electrode surfaces considered.
