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.
Claims6
In a method of operating a gas electrode employing an oxygen-containing gas;
- and a laminate oxygen cathode of a wetproofing layer containing polytetrafluoroethylene particles, an active layer containing carbon particles, and a current distributor:
- the improvement which comprises feeding the oxygen-containing gas to the oxygen cathode at blow-through pressure.
