The presented paper discusses a stability of porous Ni and Ni-Co sintered electrode in the process of hydrogen evolution from alkaline environment. Porous precursors of electrodes were prepared in the process of successive oxidation and reduction. The morphology characteristic of Ni and Ni-Co metallic sinters was carried out with the application of SEM/EDS methods. The electrochemical stability tests...
The presented paper discusses an influence of cobalt content in the nickel powder sintered electrode on electrochemical processes of hydrogen production. The studies of a samples surface were conducted with the use of SEM/EDX technique. The electrochemical properties of porous Ni-Co electrodes were examined by potentiostatic method. The authors applied a rotating electrode during those tests. The...
