Abstract : Investigations of methanol/air battery cells, using KOH electrolyte at room temperature (21C), show that current densities of 15 m A/sq cm at 0.60 V can be obtained. Single cells operated for more than 400 hours at current densities of 10 to 12 mA/sq cm constant current (0.67 to 0.80 A). These small cells had reactant-electrolyte capacities to operate for more than 40 hours on a single filling. The cells operated without a membrane or separator protection for the cathode with faradaic reactant efficiencies as high as 60% during a cycle. The anode electrode contained a Pt:Pd catalyst and the cathode electrode, a silver catalyst. (Author)
