    摘要： An electrochemical cell assembly includes an electrochemical cell including housing and a negative active material disposed within a first electrode chamber of the housing. The negative active material includes lead. The electrochemical cell further includes a positive active material disposed within a second electrode chamber of the housing and a separator disposed in the housing between the first electrode chamber and the second electrode chamber. The positive active material includes lead and/or lead dioxide. The electrochemical cell assembly further includes a pumping assembly configured to pump a plurality of electrolytes through either the first electrode chamber or the second electrode chamber during operation of the electrochemical cell based on a process of a cell cycle of the electrochemical cell.

    摘要： Ceramic proton-conducting oxide membranes are described herein, which are useful for separating steam from organic chemicals under process conditions. The membranes have a layered structure, with a dense film of the perovskite over a porous composite substrate comprising the perovskite material and a metallic material (e.g., Ni, Cu, or Pt). The perovskite comprises an ABO3-type structure, where “A” is Ba and “B” is a specified combination of Ce, Zr, and Y. The perovskite ceramic materials described herein have an empirical formula of Ba(CexZr1-x-nYn)O3-δ, wherein 0

    摘要： A method for recycling molten salt from electrorefining processes, the method having the steps of collecting actinide metal using a first plurality of cathodes from an electrolyte bath, collecting rare earths metal using a second plurality of cathodes from the electrolyte bath, inserting the collected actinide metal and uranium into the bath, and chlorinating the inserted actinide metal and uranium. Also provided is a system for recycling molten salt, the system having a vessel adapted to receive and heat electrolyte salt, a first plurality of cathodes adapted to be removably inserted into the vessel, a second plurality of cathodes adapted to be removably inserted into the vessel, an anode positioned within the vessel so as to be coaxially aligned with the vessel, and a vehicle for inserting uranium into the salt.

    摘要： Systems for creating electrodes for polymer electrolyte membrane fuel cells include an XY stage having a heated vacuum table physically coupled to the XY stage. The vacuum table has a working face with a plurality of channels formed therein to communicate vacuum pressure from a port coupled to a vacuum source to the channels. A sheet of perforated heat-conductive material has staggered holes configured to evenly distribute the vacuum pressure from the channels through the perforated sheet. A heat-conductive wire mesh is placed over the perforated sheet, and has openings smaller than the staggered holes such that a membrane material placed on the wire mesh is not deformed by the vacuum pressure. A nanopipette or micropipette coupled to a pump is configured to deposit electrode ink onto an exposed surface of the membrane material as the controller device causes the XY stage to move the vacuum table to control deposition of the electrode ink onto the surface of the membrane material.
