Abstract:

These investigations have demonstrated the feasibility of long-term operation of methanol-air battery components through life testing of more than 8000 hours. Fuel utilization efficiency, using bulk or single charge fuelelectrolyte storage techniques, has increased to 82 with changes in cell design and fabrication techniques. Each attempt to get long-term operation from multicell stacks and batteries resulted in short operational life caused by mechanical leakage, forcing termination of test. A continued investigation will be directed toward improving fabrication techniques, selecting better bonding cements, or alternatively, changing cell frame materials. Studies showed that these methanol-air batteries can operate at extremely low temperatures with anolyte solutions containing 3 M HCOOCH methyl formate in 5.5 M KOH.
