    Abstract: This is a process to generate alternating current without an external source for cell-houses in electrowinning or electrorefining of copper or other products in which the electric source consists of a conventional rectifier-transformer group that supplies continuous electrical current to the cell-house, which is connected in parallel to a device characterized by having the capacity to extract an electrical current from the cell-house for a period of time and then return it in another period of time, whether periodically or semiperiodically and without changing the average value of the electrical current, supplied to the cell-house by the rectifier-transformer. This results in a electrical current in the cell-house that is the superimposition of a continuous and alternating current. This process is designed to overcome the barrier of electric potential produced by the presence of the pure continuous electric field in cell-houses through the electric agitation of an ion-rich electrolyte.

  • Publication number: 20130062215
    Abstract: In a method of stopping an operation of a water electrolysis system, an on-off valve disposed in a pressure release line communicating with a cathode side of an electrolytic membrane is opened while an electrolytic current is applied between power feeders to electrolyze water for generating oxygen on an anode side of the electrolytic membrane and high pressure hydrogen having a higher pressure than a pressure of the oxygen on the cathode side. A value of the electrolytic current is reduced in a predetermined cycle or continuously. One of a specific resistance and conductivity of water to be supplied to the high pressure hydrogen producing apparatus is detected. The value of the electrolytic current is increased if the specific resistance is equal to or lower than a first predetermined value, or if the conductivity is equal to or higher than a second predetermined value.

  • Publication number: 20130048507
    Abstract: A water electrolysis system includes a high-pressure hydrogen production unit for electrolyzing water to generate oxygen and high-pressure hydrogen (the pressure of the high-pressure hydrogen being higher than that of the oxygen), and a gas-liquid separation unit for removing water contained in the high-pressure hydrogen. The gas-liquid separation unit is placed on a hydrogen pipe for discharging the high-pressure hydrogen from the high-pressure hydrogen production unit. In addition, the water electrolysis system includes a high-pressure hydrogen supply pipe for transferring dewatered high-pressure hydrogen from the gas-liquid separation unit, a cooling unit, which is placed on the high-pressure hydrogen supply pipe and is capable of variably controlling the temperature of the high-pressure hydrogen to adjust the humidity of the high-pressure hydrogen, and a control unit.

  • Patent number: 8163163
    Abstract: A method of electrochemical analysis using a sensor electrode specific for an analyte under test. The method comprises immersing the sensor electrode in a sample solution suspected of containing the analyte; forming an electrochemically active complex by exposure to solutions containing secondary receptors or competing molecules labelled with a charged or enzyme label; and subsequently exposing the sensor to an electrochemically active solution. The measurement step comprises driving the sensor electrode potential to a predetermined fixed potential by applying a current or activation waveform then monitoring the potential difference between the sensor electrode and a reference electrode following removal of the holding current. Current, rate and potential can all be measured and used to determine analyte concentration or sensor state.
