Thin electrodes of established structure and catalytic activity were produced in such quantity as to allow the building of fourteen 6-volt, 100-watt hydrogen-air batteries. The first six batteries were used to determine general performance parameters which served as guidelines for the life-testing program for the remaining eight batteries. The interrelationship between temperature, relative humidity and electrolyte concentration was studied. Current density polarization curves of the batteries were determined several times during the operational life of the batteries with air, and with oxygen. Tests to compare different modes of operation intermittent versus continuous and different electrolytes NaOH and KOH were started. The life-testing program includes performance checks at different temperature levels, and also a comparison between CO2-free and CO2-containing air. Author
