All-Vanadium Dual Circuit Redox Flow Battery for Renewable Hydrogen Generation and Desulfurisation

Hubert Girault, Frédéric Gumy, Pekka Eero Peljo, Heron Vrubel, Véronique Amstutz, Christopher Raymond Dennison, Kathryn Ellen Toghill, Joana Morgado, Justine Nadine Liliane Pandard

An all-vanadium dual circuit redox flow battery is an electrochemical energy storage system capable to function as a conventional battery, but also to produce hydrogen and perform desulfurization when surplus of electricity is available by chemical dischar ...

Macroscopic indicators of fault diagnosis and ageing in electrochemical double layer capacitors

Hubert Girault, Mario Paolone, Dimitri Torregrossa, Véronique Amstutz, Kathryn Ellen Toghill

The ageing behaviour of electric double layer (EDLC) supercapacitors during over-temperature and over-voltage stresses is described. Specific experimental tests were carried out in order to reproduce, under laboratory controlled conditions, the above-menti ...
