    摘要： An electrode, electrochemical cell, and electrochemical processes are disclosed. The electrode (5) is a porous, multi-layered electrode which can have an element in flexible, strip form wound around a central, usually flat plate core (4), which core (4) may serve as a current distributor. In any form, each layer can be represented by a very thin, highly flexible metal mesh (1). This can be a fine, as opposed to a coarse, mesh which has extremely thin strands (2) and small voids. The electrode (5) will have an active coating. For utilizing this electrode, the cell in one form will be a monopolar cell (40) providing upward, parallel electrolyte flow through the porous, multi-layered electrode (5). A representative cell (40) can have such electrode at least substantially filling an electrode chamber. The cells can be contained in a cell box that will provide the desired flow-through relationship for the electrolyte to the electrode. In cell operation, electrochemical processes which can be carried out include metal ion oxidation or reduction, oxidation of organic substituents, nitrate reduction as well as salt splitting.

    摘要： An aqueous electrolyte aluminum-air battery comprises one or more cells (14), each cell comprising a frame (40) which defines an electrolyte chamber (54). The frame (40) is made of a rigid material inactive to the electrolyte. The cell has a consumable aluminum anode (80) and an air cathode (90) spaced from the anode by said electrolyte chamber. Means are provided for admitting electrolyte solution into the electrolyte chamber (54). A vent (64) exposes the electrolyte chamber to atmosphere. A hydrophobic membrane (66) which is impermeable to the passage of electrolyte but permeable to the passage of hydrogen closes the vent. A surface (82) of each cell anode is exposed to the flow of air. The amount of surface exposed is effective to dissipate heat generated at the anode (80).

    摘要： The present invention resides in the discovery that a strip (12) of reticulated foam which is semi-conductive can be continuously electroplated, utilizing a cathode roll (26) which is positioned, in a first electroplating zone, outside of the electroplating bath. An anode (28) is immersed in the electroplating bath. The strip of reticulated foam is first introduced into the electroplating bath (22) and travels in the direction from the anode to the cathode roll prior to contacting the cathode roll. In this way, the strip achieves a partial plate at the anode which provides a current path between the anode and the cathode roll effective for sustaining the plating reaction in said first electroplating zone.

    摘要： A catalytic polymer electrode comprises a current conducting polymer body forming an electrode base which is provided with catalytic valve metal particles fixed to its surface. A current conducting body of carbon filled thermoplastic polymer is heated to soften its outer surface, and the catalytic valve metal particles are pressed onto its softened surface and thereby attached to the surface of the polymer body. Such a catalytic polymer electrode used as an anode in an impressed-current cathodic protection system comprises a catalyst to provide a reduced oxygen potential. Such catalytic polymer anodes may be applied in systems for impressed current cathodic protection of reinforced concrete structures, such as bridge decks, support members, parking garages, or of buried or submerged steel structures such as gas and oil pipelines, offshore production platforms, fuel storage tanks, well casings.
