Abstract

The need for energy distribution infrastructure for mobility is set to change dramatically in the near future. We have shown the advantages that stationary batteries bring to the design of filling stations for electric vehicles, before going on to discuss a particular type of stationary battery, namelyRedox Flow Batteries. We also discussed the principle and properties of vanadium batteries.

From a more fundamental point of view, we were interested in redox electrocatalysis, which consists in performing electrochemistry on electrically floating particles in the presence of redox couples. The first application of this concept is the design of solid energy " boosters " for electrolyte flow batteries. The second application is the production of hydrogen from a vanadium(II) electrolyte in acid solution.

Finally, we presented fuel cell vehicles dedicated to endurance motor racing and will discuss more generally the infrastructure requirements for hydrogen mobility.
