Journal ArticleDOI
Detection of capacity imbalance in vanadium electrolyte and its electrochemical regeneration for all-vanadium redox-flow batteries
Nataliya Roznyatovskaya,Tatjana Herr,Michael Küttinger,Matthias Fühl,Jens Noack,Karsten Pinkwart,Jens Tübke +6 more
TL;DR: A vanadium electrolyte for redox-flow batteries with different V III and V IV mole fractions has been studied by UV-vis spectroscopy as discussed by the authors, which enables a rough estimate of the V IV and V III content, which can be used to detect an electrolyte capacity imbalance.
Journal ArticleDOI
The role of phosphate additive in stabilization of sulphuric-acid-based vanadium(V) electrolyte for all-vanadium redox-flow batteries
Nataliya Roznyatovskaya,Vitaly A. Roznyatovsky,Carl-Christoph Höhne,Matthias Fühl,Tobias Gerber,Michael Küttinger,Jens Noack,Peter Fischer,Karsten Pinkwart,Jens Tübke +9 more
TL;DR: In this article, the authors investigated the role of phosphoric acid in vanadium redox-flow battery (VRFB) aggregation using variable-temperature 51V, 31P, 17O, 1H NMR spectroscopy and dynamic light scattering (DLS).
Journal ArticleDOI
Cycle behaviour of hydrogen bromine redox flow battery cells with bromine complexing agents
Michael Küttinger,Michael Küttinger,Ruben Brunetaud,Jakub Wlodarczyk,Peter Fischer,Jens Tübke,Jens Tübke +6 more
TL;DR: In this paper, the performance of hydrogen-bromine redox flow battery cells with 1-ethylpyridin-1-ium bromide ([C2Py]Br) as BCA in a bromine electrolyte with a theoretical capacity of 179.6
Journal ArticleDOI
Study of the long-term operation of a vanadium/oxygen fuel cell
Jens Noack,Gwenn Cognard,Meryem Oral,Michael Küttinger,Nataliya Roznyatovskaya,Karsten Pinkwart,Jens Tübke +6 more
TL;DR: A vanadium/oxygen fuel cell (VOFC) with a geometrically active area of 51 cm2 and two membranes was discontinuously operated over a period of over 676h with 47 successive tests at room temperature with a current density of 19.6 mA/cm2 in order to investigate signs of ageing.
Journal ArticleDOI
A coupled-physics model for the vanadium oxygen fuel cell
F.T. Wandschneider,Michael Küttinger,Jens Noack,Peter Fischer,Karsten Pinkwart,Jens Tübke,H. Nirschl +6 more
TL;DR: In this article, a stationary two-dimensional model for the vanadium oxygen fuel cell is developed, which consists of a single cell with two membranes, set up as of two half-cells and an intermediate chamber.
