Studies on palladium coated titanium foams cathode for Mg-H2O2 fuel cells

► A novel palladium coated titanium foam cathode for magnesium-hydrogen peroxide fuel cell (Mg-H2O2 fuel cell) was prepared by electrodepositing palladium onto titanium foam. ► The electrochemical measurements demonstrated that titanium foam exhibits excellent corrosion resistance compared to the cathode substrate studied before. ► The performance and stability of Mg-H2O2 fuel cell thus obtained were improved obviously.
