ABSTRACT:
This disclosure is directed to operating gas electrodes, e.g., oxygen (air) cathodes at "blow-through" pressures of oxygen-containing gas, viz., oxygen or air pressures exceeding the pressure(s) at which bubble-through of such gas occurs, which pressures result in savings due to reduced cathode potential (voltage) during operation. Depending upon the specific oxygen (air) cathode employed, the pressures required to obtain blow-through can vary widely. Usually, however, oxygen (air) pressures of 2 to 15 psig are satisfactory to accomplish blow-through.
