Electrode flow cell

Two-Dimensional Electrode Flow Cells. The simplest and least expensive cell design is the undivided parallel plate cell with electrolyte flow by some form of manifold. Electrical power is monopolar to the cell pack (72). An exploded view of the Foreman and Veatch cell is shown in Figure 7. Note that electrolyte flow is in series and that it is not easily adapted for divided cell operation.

Two parts of the 1770 system are temperature sensitive. The chemistry itself, largely due to the volatility of iodine, has a substantial temperature coefficient, and the electrode response ean vary slightly when sample temperature differs from the temperature at which the electrode was calibrated. Since it is the sum of these components that is of practical interest, we examined the system temperature, after calibration at 25 °C, in an environmental chamber. Temperature was measured directly in the electrode flow cell, and potential of the electrode monitored using a digital millivolt meter. The results appear in Figure 5. Based on this information.

Amperometric responses of GOD-PBT electrode to glucose were made in a three-electrode flow cell with 0.1 mol dm 3 phosphate buffer, pH 7.0 solution as supporting electrolyte. The schematic description of the amperometric glucose sensor is depicted in Figure 1. The flow rate was controlled at 1 ml min l by a Atto Coporation model SH-121IH perista pump. All supporting electrolyte solutions and glucose solutions were air-saturated prior to experiment. 

Two types of EC-NMR experiments have been carried out electrode potential-dependent studies of an adsorbate ( CO, CN) at room temperature [6, 8, 24], and temperature-dependent studies of an adsorbate [5, 10] and of platinum electrocatalysts [7, 25], down 10 K. For all of the EC-NMR measurements, the electrode materials, either polycrystalline platinum black or carbon-supported commercial fuel cell grade platinum electrodes, were immersed in a supporting electrolyte, typically 0.5 M H2SO4. For temperature-dependence studies, EC-NMR samples are prepared in a conventional three-electrode flow cell with oxygen-free N2 or Ar as a protecting gas, then together with supporting electrolyte and under the protection of...
