In this paper the anodic polarization performance of a pure nickel ele
ctrode and a nickel electrode modified by electrodeposition of niobium
have been investigated. It is found that the anodic polarization char
acteristics of the nickel electrode is improved significantly by the d
eposition of niobium. The improvement is partially attributed to the i
ncrease in surface area of the nickel electrode and the increase in el
ectrocatalytic activity, but is caused mainly by improvement in the we
ttability of the electrode. (C) 1998 Elsevier Science S.A.
