High temperature electrochemical studies using a channel flow cell heated by radio frequency radiation

Systems involving one and two electron redox reactions were studied under h ydrothermal conditions using a novel hydrodynamic method based on a convent ional channel flow cell where the working electrode was heated by radio fre quency radiation. The diffusion activation parameters obtained with the rad io frequency channel cell were compared with independent data from microele ctrode high temperature experiments and analysed in terms of the Stokes-Ein stein equation.
