Analysis of Energy Canversion of Three Compartments Dialytic Battery with Ion-Exchange Membranes

Membrane Conversion Process of the Free Energy of Mixing (Part 2)

Abstract

An investigation was conducted on the energy conversion characteristics of the battery in which the initial concentration of sodium chloride in the electrode compartments and in the middle was 3.5×10⁴ mg/l and 350mg/l, respectively. The power conversion efliciencies which are defined as the ratio of power obtained and the maximum available free energy difference between the initial and the final stages, were 12 to 0.5%. The current conversion efficiencies defined as the ratio of the charge transferred and salt transferred were 10 to 0.5%.
