Generation of EMF in the rotating electrochemical cell

Based on the literature data and calculated results, the emf, which is generated in the rotating electrochemical cell with the electrodes located at different distances from the rotation axis, is estimated in the cases that the system is or is not placed in the magnetic field. These data enable one to determine the conditions (the angular cell rotational rate, the magnetic induction, etc.), under which the required emf can be obtained without an external power source. The application of magnetic field enables one increase the emf from several mV to several volts.
