Ion membrane voltage efficiency

The voltage efficiency formula is: the percentage of the theoretical decomposition voltage relative to the actual slot voltage, that is, V0/V × 100%. The actual slot voltage V is given by V = V0 + n_positive + |n_negative| + the total ohmic voltage drop. V0 is the theoretical breakdown voltage, that is, the slot voltage when the operating current is 0 ； n+ and n- represent the overpotentials of the diodes ； The total ohmic voltage drop refers to the sum of the ohmic voltage drops when current flows through various parts of the electrolyzer. V0 can be calculated using thermodynamics ； The overpotential is determined by the electrode material and manufacturing process, and it is a key aspect of electrode reaction kinetics ； For the total ohmic voltage drop, the resistance of the electrolyte is much greater than that of the electrodes, and the electrolyte resistance is greatly affected by bubbles. For actual production, the actual cell voltage can be measured ； It is only necessary to determine the value of V0 through thermodynamic calculations based on the operating conditions in order to calculate the voltage efficiency. Additionally, the supplier should be able to provide the V0 value for their experimental cells, although there may be some differences compared to actual production conditions.

Voltage efficiency is the theoretical decomposition voltage divided by the measured voltage; the decomposition voltage should be provided at the time of delivery.
