Phosphate Modified Copper Electrodes for Methanol Fuel Cell

this work aims to investigate the electro oxidation of methanol, in alkaline solution at a copper electrode modified with electrodeposited natural phosphate and nickel (ni-np/cu), by cyclic voltammetry, impedance measurements and square wave voltammetry. morphological characterizations were performed by sem and xrd techniques. it was found that ni dispersed on natural phosphate (np) shows a catalytic activity towards methanol oxidation better than massive ni. ni and np were fixed on copper electrode by electro deposition using potentiostatic and galvanostatic techniques.
