    Abstract: An electrolytic ozone cell anode spring fastening board structure includes a solid polymer electrolyte membrane (1), an anode electrocatalyst layer (2), a diffusion layer (3), frame body and support parts (5). A diffusion layer counterpiece (4) has one side attached to the diffusion layer (3), the other side of the diffusion layer counterpiece (4) equipped with a centered elevated step, which contacts the center of the convex side of a spherical spring board (6). In addition, the solid polymer electrolyte membrane (1), frame body and support parts (5), diffusion layer (3), diffusion layer counterpiece (4) and spring board (6) are held together by mechanical fastening means. It prevents a decrease in ozone generation rate in electrolytic ozone cell that can occur from the metal board deformation and thinning of the anode electrocatalyst layer.

  • Patent number: 8303795
    Abstract: In the method and system, a number of electrolytic cells are arranged as a cell group, which cells are separated by a number of partition walls; in each cell, a number of anodes and cathodes are arranged in an alternating order, so that in each cell, next to each anode, there is arranged a cathode, and so that in each cell, each individual anode is fitted in the same anode line with the anode of the adjacent cell, and in each cell, each individual cathode is fitted in the same cathode line with the cathode of the adjacent cell, and each anode is galvanically connected to at least one cathode of the adjacent cell. The flowing direction of the current passing in the cell group is deviated in different directions in order to make the current flow mainly in the direction of the cell group.

  • Patent number: 8236151
    Abstract: A carrier provides the ability to perform wet chemical processing on substrates using low cost equipment inspired by the electroplating methods typically utilized in leadframe-based semiconductor packaging or printed circuit board industries. Two frame pieces are mated together to form the carrier which enables transport of at least one substrate through wet chemical processing and includes a non-conductive frame with an exposed conductive flange to allow electrical coupling with processing equipment. Electrical contacts within the non-conductive frame make contact with the at least one substrate and are coupled to the conductive flange allowing an electrical potential to develop across the substrate while undergoing processing within the electroplating equipment.

  • Publication number: 20120160704
    Abstract: Modular anode assemblies are used in electrolytic oxide reduction systems for scalable reduced metal production via electrolysis. Assemblies include a channel frame connected to several anode rods extending into an electrolyte. An electrical system powers the rods while being insulated from the channel frame. A cooling system removes heat from anode rods and the electrical system. An anode guard attaches to the channel frame to prevent accidental electrocution or damage during handling or repositioning. Each anode rod may be divided into upper and lower sections to permit easy repair and swapping out of lower sections. The modular assemblies may have standardized components to permit placement at multiple points within a reducing system. Example methods may operate an electrolytic oxide reduction system by positioning the modular anode assemblies in the reduction system and applying electrical power to the plurality of anode assemblies.
