“…(3) Where ∆ν is the amount of sulphuric acid, transferred in electrochemical processes, z is the number of electrons, participating in reaction, and F ia a Faraday constant. The average value of voltage was calculated as (4) Where and is the voltage on resistance R at the initial and final stage of the process. This values were determined in experiment, because it is difficult to predict the electrochemical overvoltage of the electrodes in theoretical calculations.…”

In our research we studied the efficiency of converting low-grade heat into electrical energy. The studied cycle is based on sulphuric acid solutions separation in temperature gradient and further electricity generation in concentration galvanic cell. In our calculations we used combined method. To calculate obtained electrical energy we used experimental date, because it is rather difficult to predict electrodes overpotential. The heat, consumed in distilling process, was calculated in theory. As the result of calculations it was shown that if temperature difference is 20 K (T1=300K and T2=280 K) the efficiency of the cycle is about 1.5 percent (about 23% of Carnot cycle efficiency). Such temperature difference could be provided, for example, by vertical thermal gradient of the ocean.

“…Ocean is perspective source of renewable energy. Ocean energy -it is not only the energy of waves and currents [1][2][3][4][5][6], but also the energy of vertical thermal gradient [7][8][9][10]. In some arrears of the ocean temperature difference between the surface of the deep layers of the water could reach 20-25 C 0 .…”
