Output Characteristics Of A Circular Cone Type Graphite Cathode For Al-Cl-2 Fuel Cells In Alcl3-Emic Ionic Liquid

To improve the reduction efficiency of chlorine electrodes in aluminum-chlorine cells, this reports a circular cone type graphite cathode, with an electrochemical cell consisting of an aluminum anode and the graphite cathode evaluated in EMIC-AlCl3 ionic liquid.The current density in the circular cone type cathodes with different cone angles exhibited a maximum value at 40, and the current density at cell voltage of 0.5 V was about 25 mA cm(-2). This value is about 80% larger than that of a cylindrical type graphite cathode. In a circular cone type cathode with a 40 angle, the maximum power density recorded was 15.3 mW cm(-2).
