Electrochemical behavior of metal hydrides
Janis Kleperis,Grażyna Wójcik,Andrzej Czerwiński,J. M. Skowroński,Maciej Kopczyk,Maria Bełtowska-Brzezinska +5 more
TL;DR: In this article, the effect of the chemical nature and stoichiometry of specific alloy families (AB5, A2B, AB/AB2 and AB2) on the hydride stability, hydrogen storage capacity and kinetics of hydrogen sorption-desorption in the solid phase/gas and solid phase-electrolyte solution systems is discussed.
Journal ArticleDOI
Electrochemical behavior of lead in sulfuric acid solutions
Andrzej Czerwiński,Malgorzata Żelazowska,M. Grdeń,K. Kuc,J.D. Milewski,A. Nowacki,Grażyna Wójcik,Maciej Kopczyk +7 more
TL;DR: In this article, the electrochemical behavior of the lead electrode has been studied by cyclic voltammetry (CV) in sulfuric acid solutions, with concentrations ranging from 0.05 to 5 M.
Journal ArticleDOI
Electrochemical behavior of nickel deposited on reticulated vitreous carbon
Andrzej Czerwiński,M. Dmochowska,M. Grdeń,Maciej Kopczyk,Grażyna Wójcik,G. Młynarek,J. Kołata,J. M. Skowroński +7 more
TL;DR: In this paper, the electrochemical performance of reticulated vitreous carbon (RVC) has been investigated in solutions of KOH and showed that the RVC covered with nickel is a good carrier for Ni(OH) 2 /NiOOH.

Electrochemical behaviour of multicomponent ZrTiVMnCrNi alloys in alkaline solution
Grażyna Wójcik,Maciej Kopczyk,Grażyna Mlynarek,Wlodzimierz Majchrzyckia,Maria Beltowska-Brzezinska +4 more
TL;DR: In this article, the effect of the composition of multicomponent Ni alloys on their hydrogen storage capacity and on the rate of electrosorption/desorption of hydrogen was investigated under potentiodynamic as well as single-pulse and long-term galvanostatic conditions.
