    摘要： Disclosed are methods for rejuvenation of oxygen electrodes which maximize the power efficiency available from such oxygen electrodes while minimizing the voltage necessary to operate such oxygen electrodes over extended periods of time. These methods include in situ and out of cell techniques using hot water washing followed by air drying and dilute acid washing followed by air drying.

    摘要： Disclosed are gas fed, porous electrodes capable of steady, high current density operation for practical periods of service, e.g. as oxygen cathodes in metal-air batteries. The subject electrodes feature at least two bonded composite layers, one of which is a form-stable, conductive wetproofing layer while the other is an unusually thin active layer containing active carbon particles predominantly between about 2 and about 20 micrometers and having a high internal surface area, e.g. a B.E.T. surface area of over 1000 m.sup.2 /gram. A simple and highly successful method of preparing such electrodes is also disclosed, which avoids the necessity of separately forming and handling the thin active layer.

    摘要： This disclosure is directed to preparing deashed, precious metal catalyst-containing, partially fluorinated active carbon particles of the formula CF.sub.x, where x ranges from 0.1 to about 0.18, preferably using either platinum or silver as the catalyzing material, which can be incorporated into an active layer component of a gas electrode, e.g., an oxygen (air) cathode suitable for use in a chlor-alkali electrolytic cell for producing chlorine and caustic while conserving electrical energy. These particles are deashed to have a B.E.T. surface area of at least 600 m.sup.2 /g and contain less than about 4 weight percent ash. Active electrode layers containing such particles demonstrate an unusually desirable combination of resistance to corrosion, retention of conductive properties and retention of catalytic surface area.

    摘要： The active layer of an electrode is laminated on its working surface to a current distributor and on its opposite surface to a porous coherent, hydrophobic, wetproofing layer. The active layer contains from about 60 to about 85 wt. % active carbon particles bound in a matrix of a fibrillated mixture of a fluorocarbon polymer and carbon black. The electrode is useful in chlor-alkali cells.

    摘要： This disclosure is directed to a gas diffusion electrode, e.g., an oxygen (air) electrode, having a conductive, porous, sintered, plaque metal substrate containing generally spherically-shaped anchor site depressions on its active layer-contacting surface; an active layer containing catalyzed or uncatalyzed carbon particles and whose plaque-contacting surface includes anchor portions which interlock with the anchor site depressions and assist in securing the active layer to the plaque substrate, and a hydrophobic backing (wetproofing) layer in contact with the other surface of the active layer. The plaque is made by forming, e.g., by rolling or pressing, the metal powder, preferably silver, containing particulate extractable material on one face or surface thereof into a thin plaque; sintering the plaque containing the extractable material at temperatures of from about 1000.degree. to about 1300.degree. F. for time periods of from about 2 to about 30 minutes and thereafter removing the extractable material to produce a plaque electrode substrate having anchor site depressions in one surface. The active layer material is then deposited, preferably by filtration, on the plaque surface having such depressions followed by depositing the hydrophobic layer, also preferably by filtration.
