    摘要： A process for making a catalytic electrode containing a transition metal nano-catalyst without using spray or thermal decomposition, and a process for making an electrochemical cell with a catalytic electrode. The nano-catalyst is a particulate material that includes particles that are at least partially oxidized, preferably to include at least oxide shells, before mixing with an activated carbon and binder in a liquid medium to adhere particles of the nano-catalyst to internal and external surfaces of the particles of activated carbon. Oxidation of the nano-catalyst particles allows the mixing of the nano-catalyst, activated carbon and binder in air rather than an inert gas atmosphere and can avoid the use of potentially dangerous liquid media such as highly volatile alcohols.

    摘要： A device and system useful for highly efficient chemical and electrochemical reactions is described. The device comprises a preferably porous electrode and a plurality of suspended nanoparticles diffused within the void volume of the electrode when used within an electrolyte. The device is suitable within a system having a first and second chamber preferably positioned vertically or in other special arrangements with respect to each other, and each chamber containing an electrode and electrolyte with suspended nanoparticles therein. When reactive metal particles are diffused into the electrode structure and suspended in electrolyte by gasses, a fluidized bed is established. The reaction efficiency is increased and products can be produced at a higher rate. When an electrolysis device can be operated such that incoming reactants and outgoing products enter and exit from opposite faces of an electrode, reaction rate and efficiency are improved. Ideally, this device and system can be used to rapidly produce significant quantities of high purity hydrogen gas with minimal electricity cost.

    摘要： A process for making a catalytic electrode, a process for making an electrochemical cell with a catalytic electrode, and an electrochemical cell made according to the process. The catalytic electrode has an active layer comprising a catalytic material, an electrically conductive material and a binder, and a gas diffusion layer including a material that is permeable to gas entering or escaping from the cell but essentially impermeable to electrolyte. The gas diffusion layer is adhered to the active layer by a patterned pressure bonding process to provide the catalytic electrode in which the entire gas diffusion area is adhered to the active layer, with areas of relatively high and relatively low adhesion. The electrode has a high overall bond strength, and the permeability of the gas diffusion layer remains high it has been adhered to the active layer to provide excellent high power capability.

    摘要： An elongate air depolarized electrochemical cell (10). A grommet (18) closes the top of the cell (10). A seal (36) can extend upwardly into a slot (174) between the grommet (18) and a top closure member (177) such as at the top of a cathode can (28), or a separate top closure member (200). Cathode assembly (26) and separator (16) can extend into the slot (174). The seal is between the grommet (18) and cathode assembly (26), or between grommet (18) and separator (16). or both. The seal can extend upwardly into the slot (174) from an outer surface of the cathode assembly (26), can extend about respective upper edges of the cathode current collector (57), catalyst, and separator (16), and downwardly toward, preferably against or along the inner surface of, the separator (16). The top closure member (200) can be crimped against the grommet (18) at the slot (174), with the cathode assembly (26), and optionally the separator (16), in the slot (174) between the grommet (18) and the top closure (200), thus to provide a liquid-tight crimp seal. The top closure (200) can be crimped first against the grommet (18) at the slot (174), and further crimped against the grommet (18) at a second locus (178) displaced longitudinally from the first crimp. Composition of the seal comprises a microporous polymer (36), preferably polytetrafluoroethylene. Preferred embodiments comprise at least two, preferably at least three, layers of air permeable microporous sheet material, useful for diffusion of air therethrough to the cathode reaction surface (63). The layers are wrapped continuously and without intervening end, to form an outer surface of the cathode assembly (26). Another expression of the invention is a cathode assembly (26), or cathode-separator combination, for use in an elongate air depolarized cell (10). The air permeable sheet material (36), as wrapped about the tubular cathode assembly, is compressed so as to have a compressed thickness less than the uncompressed thickness. The invention still further comprehends an elongate air depolarized cell (10) comprising an anode, a cathode, or cathode-separator combination as described herein, and electrolyte.

    摘要： An elongate, generally tubular, air depolarized electrochemical cell (10) comprising a cathode (14), including an air cathode assembly (26), extending about the tubular circumference, and along the tubular length, of the cell (10), an anode (12). a separator (16) between the anode (12) and the cathode (14), electrolyte, a top closure member (177, 200), and a bottom closure member (114, 202). The cathode assembly (26) is fixedly held, by a friction fit, in a slot (116) at the bottom of the cell. The slot can be developed, for example, by inner (110) and outer (114) walls of a cathode can (28), by inner (226) and outer (224) walls of a bottom closure member (202), or by an outer wall (114) of a cathode can (28) and an opposing outer wall of a plug (128) on the interior of the cell. Preferably, bottom closure structure of the cell (10) and receives a bottom edge portion (44) of the cathode current collector (32), and makes electrical contact with the bottom edge portion (44), preferably at an inner surface (60) of the cathode current collector. A diffusion member (36) of the cathode assembly (26) is preferably compressed as a seal, at the bottom of the cell (10), between an outer side wall (39) of the cell and the remainder of the cathode assembly (26). The diffusion member (36) is also used at least as an assist in sealing the cell (10) against electrolyte leakage from the anode cavity (137) and past the cathode assembly (26). The tubular cathode current collector (32) has novel border regions (42, 44, 46. 48), novel longitudinal joint structure (54), novel perforations (56), and including novel methods of making such cathode current collectors (32) and such cells (10).

    摘要： A gas diffusion cathode for electrochemical cells provides higher power capability through the use of nano-particle catalysts. The catalysts comprise nanometer-sized particles of transition metals such as nickel, cobalt, manganese, iron, palladium, ruthenium, gold, silver, and lead, as well as alloys thereof, and respective oxides. These catalysts can substantially replace or eliminate platinum as a catalyst for oxygen reduction. Cathodes using such catalysts have applications to metal-air batteries, hydrogen fuel cells (PEMFCs), direct methanol fuel cells (DMFCs), direct oxidation fuel cells (DOFCs), and other air breathing electrochemical systems.
