Electrochemical cell having a plurality of battery stacks

Abstract: Electrochemical cell having at least two battery stacks each including an electrode assembly wound on a spool. Each electrode assembly includes two elongated electrode structures, an anode electrode structure and a cathode current collector structure. The electrode structures are wound around the center post of the spool with the anode electrode structure making contact with one of the conductive flanges of the spool and the cathode current collector structure making electrical contact with the other conductive flange of the spool. The flanges in contact with the anode structures of the battery stacks are connected to one external terminal of the cell, and the flanges in contact with the cathode current collector structures of the battery stacks are connected to another external terminal of the cell.

Connectors for conductor rails

Abstract: A connector 2 for conductor rails 1 has a portion 3 of increased diameter, along which the current collector shoe travels as it passes from one rail section to the other. The connector may be hollow with a slot 4 extending throughout its length, the slot being widened at 8 to permit the insertion of a power conductor.

Impulse release reacting upon the advanced wear of a sliding carbon contact of current collectors forming part of sliding-contact lines.

Abstract: of EP0093322In sliding-contact line systems there is the requirement to change the sliding carbon contact (211) wear component forming part of the current collectors (21) with such promptness that an unmonitored failure of loads supplied via the current collectors (21) is avoided. For this purpose, it is proposed to assign a mechanical pulse trigger (31) to the sliding-contact line (11, 12), which trigger is acted upon by the corresponding current collector (21) in the case of advanced wear of the sliding carbon contact (211) and triggers an electric pulse which leads to an indication of the requirement for the sliding carbon contact (211) to be changed.

Rocker for current collectors

Abstract: A rocker for current collectors of electrical power units with overhead line supply has two contact element carriers (3) which are arranged one behind the other in the travel direction and, in order to achieve a particularly favourable spring characteristic, are attached independently of one another via bar springs (1) to a top tube connected to the current collector. The bar springs (1) are supported at least from below between the top tube (6) and the contact element carriers (3).

Assembly for the transmission of electrical energy to vehicles

Abstract: An assembly for the transmission of electrical energy to a vehicle comprises two current rails with respective contact surfaces inclined at an angle toward each other in a roof-like arrangement and a current collector having a sliding shoe with a pair of contact surfaces inclined toward each other at the same angle. The sliding shoe is mounted movably on the current collector by means of a ball and socket joint. The support point of the sliding shoe, i.e. the geometrical center of the support ball, is located at least approximately on an imaginary line which connects the centers of gravity of the two contact surfaces of the current rails.

Power supplying device for motor driven self-traveling truck on crossing rails

Abstract: PURPOSE:To improve the safety of a power supplying device by deenergizing a current collector which is not contacted with a trolley wire. CONSTITUTION:When a truck 11 travels on rails 1 toward a turntable 14, power is supplied to the truck 11 from a trolley wire 5 through current collectors 8, 10. When the truck 11 transfers from the rails 11 to rails 4 on the turntable 14, the collector 10 is removed out of the wire 5, power is continuously supplied via the collector 8, and the truck 11 travels to the prescribed position. When the turntable 14 is rotated counterclockwise at 90 deg., a trolley wire 7 is contacted with the collector 10, and a trolley wire 6 is contacted with the collector 9. An electromagnetic contactor closes its contact when the collectors 8, 9 make contact with the trolley wires, thereby supplying power to the truck.

Current collector for route-bound electric vehicles

Abstract: A current collector for route-bound electric vehicles, such as locomotives, trams, buses or the like moving under overhead lines, is disclosed, in which, for the purpose of punctually detecting a necessary contact element change of the current collector, an optical waveguide is arranged along a wear limit, of the contact element, provided at a distance from the surface of the contact. The destruction of the optical waveguide when the predetermined wear limit is reached is converted into a warning signal which indicates to the driver the necessity of changing the contact element.

Fuel cell and its production method

Abstract: PURPOSE:To produce a fuel cell maintaining stable outputs, non-vulnerable to a mechanical impetus, and with an excellent assembling feature by inserting a metal net, i.e., current collector between a positive ion exchange film and a gas diffusion layer so as to unite three of them in one body. CONSTITUTION:A platinum net 2 concurrently serving as current collector is put into a close contact with a positive ion exchange film 1 so that the net 2 is half buried in the film 1 softened by hot press. On the other hand, a gas diffusion layer 3 made by sintering teflon powder and platinum black is mounted on the half exposed film of the net 2 to be united in one body by hot press. This consolidated material is used for methanol-air fuel cell, for instance. In this cell, an anode electrolyte 5 including methanol as a fuel is oxidized by an anode 4 and is decomposed into protons, electrons, and CO2. Protons are moved to the layer 3 through the film 1 and electrons are moved from the anode 4 through an external circuit to the layer 3, where both are combined with O2 in the air to perform a cathode reaction. CO2 is discharged through an outlet 7.

Production method of nonaqueous electrolyte cell

Abstract: PURPOSE:To obtain a nonaqueous electrolyte cell not swelling even when stored at a high temperature by immersing an anode previously in a nonaqueous electrolyte or its solvent to apply a heat treatment before the anode is assembled in the cell. CONSTITUTION:A gasket 3 is coupled with an anode can 1 soldered with an anode current collector 4, and an anode 5 and a separator 6 impregnated with a nonaqueous electrolyte are assembled. Then, the nonaqueous electrolyte 9 is injected, and next a cathode can 2 previously pressed with a light metal cathode 7 is coupled so as to be buried into the gasket 3. Under this condition, the collar section 1a of the can 1 is caulked from the periphery to the inside to complete the assembly. The anode 5 is immersed previously in the electrolyte 9 or its solvent to apply a heat treatment before the anode 5 is assembled into the cell so as to allow the anode 5 to be fully familiarized with the electrolyte 9. Thereby, the cell is prevented from swelling due to gases generated by the decomposition of the electrolyte when the nonaqueous electrolyte cell is kept in store at a high temperature after its assembly.
