Investigations of methanolair battery cells, using KOH electrolyte at room temperature 21C, show that current densities of 15 m Asq cm at 0.60 V can be obtained. Single cells operated for more than 400 hours at current densities of 10 to 12 mAsq 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 PtPd catalyst and the cathode electrode, a silver catalyst. Author
