Optimization Study of Membrane Electrolyzer for Vanadium Electrolytes Preparation

Popis výsledku v původním jazyce

In this work, the testing membrane cell of VRFB was developed. The stable round-trip energy efficiency of 82 % at a current density of 100 mA/cm2 was achieved. The battery characteristics (i.e., efficiency and current density) are acceptable for the industrial utilization of the system. The development of the device for the electrolyte production is an integral part of the successful progress during the scale-up of the VRFB. The method for the electrolyte production is based on the reductive dissolutionof the vanadium(V) oxide in diluted sulfuric acid. In this work, the design, the construction and the evaluation of two membrane flow electrolyzers of different geometries (i.e., planparallel and coaxial) for the electrolyte preparation is presented. The constructed devices replaced our systems of previous generations. The innovation in the new devices consists in the production capacity scale up (from approximately 200 ml/day to more than 5 l/day). Optimal operating conditions of both
