In the present research, a new technology was developed to produce hydrogen and electricity simultaneously from methanol. The process was performed by an electrochemical cell which is composed of a Pt-Ru/C anode, a platinum foil cathode and a bipolar membrane to separate the anode and cathode chambers. In the designed electrochemical cell, hydrogen can be produced on cathode while methanol can be oxidized on anode, respectively with additional electricity production. The hydrogen and electricity production performance in the cell was evaluated. The effect of anode surface area on hydrogen production rate and power output was also investigated. With anode apparent surface area of 6.15 cm2 , hydrogen production rate can reach up to 0.76 m3H2 m-3 d-1 and the maximum power density of 0.42 W m-2 could be achieved, respectively.

Keywords:electricity; hydrogen; methanol; bipolar membrane
