Abstract
We viewed a redox galvanic cell with copper and platinum electrodes in an electrolyte of copper(II) sulfate and studied the chemical equilibrium between the Cu1+ and Cu2+. The basis of the work of the cell is the ability to continuously generate electromotive force (EMF) by absorbing external heat. The cell is charged by an endothermic reaction, accumulating the reduced form of copper (Cu1+), the number of which is limited thermodynamically, and is discharged by oxidation of Cu1+ to Cu2+ on the surface of copper electrode. In this work we investigated the dependence of the electromotive force of the temperature and a long continuous operation with a voltage of 1.5 mV and thermodynamic efficiency of 45%.
