A Mixed Acid Based Vanadium–cerium Redox Flow Battery with a Zero-gap Serpentine Architecture

This paper presents the performance of a vanadium–cerium redox flow battery using conventional and zero-gap serpentine architectures. Mixed-acid solutions based on methanesulfonate-sulfate anions (molar ratio 3:1) are used to enhance the solubilities of the vanadium (>2.0 mol dm−3) and cerium spe...
