Abstract

The direct methanol fuel cells (DMFC) have recently received a good deal of attention in both mobile and stationary applications due to their advantages of low operating temperature (<100 ○C), easy transportation and storage of fuel, high-energy efficiency and fast start-up of fuel. The mechanism and kinetics of methanol oxidation have been studied under a wide range of conditions and on a variety of electrodes including Pt, binary and ternary alloys, modified electrodes, nano-composites and nickel. One approach to the development of DMFC is to use alkaline electrolyte which is based on the assumption that electro-catalysis is generally more facile and inexpensive in this medium[1]. The purpose of the present work is to study the electrochemical oxidation of methanol on a nickel modified glassy carbon electrode in a solution of 1 M NaOH.
