20130321111 | Magnetizer utilizing rotated assemblies of permanent magnets - Magnetohydrodynamics (MHD) has applications in all electrochemical processes and in a few that are not totally electrochemical in nature. By magnetizing the electrodes or the current collectors through the electrodes so that the vertical, closely and appropriately spaced magnetized electrodes produce a uniform, low magnetic field between them, north pole to south pole, the Lorentz force enhances the natural or forced convection where it is the greatest, very near the electrodes.

Other treatments such as adding an indifferent paramagnetic ion, an indifferent free radical, completing the magnetic circuit, using a spacer which does not obscure the electrode surface, further reduce the internal resistance, lowering the wasted energy which usually appears as heat in the electrolyte. | 12-05-2013 |
