Aqueous methanol eletrolysis using proton conducting membrane for hydrogen production

In this paper, we present the studies carried out on electrolysis of aqueous methanol for hydrogen production, in a PEM electrolyser consisting of Pt-Ru/C anode, Pt/C cathode and Nafion membrane as the electrolyte. The effect of various parameters such as methanol concentration, cell voltage, temperature, membrane thickness etc. on cell performance was investigated. The results illustrate the attractive features and indicate suitability of aqueous methanol electrolysis for distributed hydrogen production. (C) 2008 International Association for Hydrogen Energy.
