英文摘要	a novel multiscale pd-ag catalyzed porous cathode for the magnesium-hydrogen peroxide fuel cell was prepared by electrodeposition of pd onto ag coated nickel foam surface from an aqueous solution of palladium chloride. the structure, morphology and composition of the electrodeposited catalyst layer were characterized using sem, eds and xps analysis. magnesium-hydrogen peroxide fuel cell tests with the pd-ag deposited cathode were carried out and compared with the ag-deposited electrode. the effects of temperature, h2o2 flow rate and h2o2 concentration on cell performance were investigated, and the electrode stability test was carried out. the pd-ag deposited electrode showed higher catalytic activity for the reduction of hydrogen peroxide than that of the ag-deposited ni foam cathode, and gave much improved fuel cell performance. the magnesium-hydrogen peroxide fuel cell with nanostructured pd-ag coated nickel foam cathode presented a maximum power density of 140 mw cm(-2), but the mg-h2o2 fuel cell with ag coated ni foam cathode gave only 110 mw cm(-2) under the same operation condition.
