Influence of Cobalt Content on the Process of Hydrogen Evolution on the Ni-Co Porous Electrode

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 current-potential relationship was obtained at 40 degrees C in 1 molar KOH with Hg vertical bar HgO reference electrode, i.e. under conditions similar to the industrial process of hydrogen production.
