Membrane Electrolyzer for Vanadium Based Solutions

Popis výsledku v původním jazyce

Non-stable and hardly predictable power from renewable sources (e.g., solar or wind power plants) demands effective management on the power transmission level. Engineering development of new local energy storages as a part of the modern transmission network tailored to efficient and smart electricity distribution is vitally needed. Vanadium redox flow battery (VRFB), using vanadium ions in four different oxidation states (II, III, IV and V) in electrolytes, excels as the stationary energy storage in itssufficient capacity (kWh) proportional mainly to the electrolyte volume, long lifetime and high efficiency. In this work, the testing membrane cell of VRFB was continuously tested. The stable round-trip energy efficiency higher than 82 % at a current density of 100 mA/cm2 was achieved. The battery characteristics (i.e., efficiency and current density) are nowadays acceptable for the industrial utilization of the system. The development of the device for the electrolyte production is an
