Abstract
We investigate a dependence of the electromotive force (EMF) on electric field in the system “electrode–electrolyte –capacitor electrode”. The capacitor electrode is a plate of ferroelectric ceramics, on one of the surfaces of which the solid electrode is deposited and there is a mesh electrode on the other surface. When a voltage is applied to these electrodes, EMF changes or appears, if it was not before, due to changes in the concentration of ions near the mesh electrode. Shorting of the electrodes in the electrolyte through resistor R leads to arising the flow of electric current and also absorbing and emitting Peltier heat in electrodes contacting with electrolyte. In this case, greater heat absorbs compared with the emitted heat, supporting EMF , i.e. ambient heat converts into electrical energy. We also show that similar phenomenon of creating EMF takes place in structure “metal–insulator–semiconductor–metal” (MISM) .
