Abstract
In the recent years, every area of engineering related to energy has found a strong limitation
in the field of energy storage. The main problem has appeared with the emergence of
renewable generation, which provides cleaner and cheaper energy, but triggers management
difficulties to the system operators. Also, the need to find compact energy storage
systems has become an urgent demand in sectors like transport. Finally, there is an important
commitment for the big energy consumers to increase their energetic efficiency,
and the energy storage systems are specially suitable for this purpose. In this thesis, the
topic of energy storage will be dealt from the perspective of an emergent technology: the
Redox Flow Batteries. The aim of this study is to contribute to the knowledge on the field
of the performance of such batteries inside the scientific community. The focus of the
study will be the mass transport phenomena that occurs inside the electrodes in which the
redox chemical reaction that provides the electric energy takes place.
The model of the redox flow battery has been developed from the traditional batteries, in
which a porous media catalyzed the reaction of the species. The main feature that contributed
to the initial success of the idea of the RFB was the capability that this type of
systems showed to decouple energy from power. However, the models were optimized
for the past technologies, but not for the flow batteries. The aim of this study is to understand
the parameters underlying the tranport phenomena in the electrodes and their
effects. Such knowledge can be completed with other reaserch projects in which other
characteristics of the flow batteries are studied, and finally a complete model can be built
in order to optimize the overall performance of the RFBs.
