Flow Channel Cell Apparatus for High Rate Electrolysis Studies

Abstract

A simple flow channel cell apparatus is described which is suited for high rate electrolysis studies under well controlled hydrodynamic conditions. The design includes a discontinuously operated piston pump which presses the electrolyte through the electrochemical cell at linear velocities of up to 2000 cm/sec. An electrolyte volume of less than 2 liters is required for the operation of the apparatus. No metal parts except the electrodes are in contact with the solution. Mass transfercharacteristics of the flow channel cell have been determined by measuring limiting currents for the reduction of ferricyanide.
