Definitions

  • the invention refers to electric energy production, using electric (electric-galvanic) cells.
  • Electric cells are used to convert chemical to electric energy and vice versa.
  • charge energy has to be consumed.
  • the charge energy equals the discharge one (reverse processes are assumed). In this way, a cell can be used only for energy storage.
  • the use of hydrogen fuel cells is hydrogen consuming.
  • the difference of this invention is that the cell charge (when we offer power), takes place in a different solution from that of the discharge (we take power). We select the solutions so that the electromotive force (emf) during charging is lower than that of discharging. The difference is the useful power. Solutions concentration change during cells operation. Electrolyte is transferred from one solution to the other. Heat is used for this process.
  • the poles are connected through an electrice source HTI,the voltage of which is reverse and a little higher from the emf of the poles. A current of reverse direction will flow and OiJLn + ions will move toward the electrodes.
  • the original solution may be concentrated from the beginning (M2 instead of Ml) so that crystals will be created without temperature change imposition.
  • Crystals may enter the saturated solution (M4).Dissolution will take place during cell operation(as electrolyte ions move to electrodes) and the solution concentration will remain constant.
  • the heat exchanged by the system is a)crystallization enthalpy offered to (absorbed by) the system through heat exchanger is ql 11 ⁇ 111 H MISOI , where m the crystal moles and H M I SO I the solution enthalpy at concentration Ml and temperature Tl b)heat evolved (rejected )during crystals solution ,where HM 3so ithe solution enthalpy at concentration M3and temperature T3.
  • a cycle has been completed since the two solutions recover their original concentration and the electrodes their original form.
  • the electric power that is offered by the cell may be higher from that consumed for recharge. ⁇ G of many solvents, are so different, as to create a satisfactory voltage difference. Removing of first solution particles from the second solution may need, in case such particle are transferred by the electrolyte.
  • electric power is offered by the cell when electrolyte ions are moved towards the electrodes (It may be attained by using the convenient solution). We bring these products together, so that they react forming the original electrolyte. This electrolyte dissolves into the solution, restoring the initial concentration. The cycle is completed.
  • a volatile electrolyte is used, so that two gases are released from the electrodes while we take electrical energy. We bring the gases together and they react reforming the electrolyte which is again dissolved in the solution.
