The electrochemical reactors have been used for more than a century in much industry. The metal production such as aluminum production or gas production such as chlorine production are the main industries that use electrochemical reactors. Nowadays, in the context of the spread of renewable energies the electrochemical devices have been successful applied to energy storage (e.g. power to gas). Moreover, the electrochemical technics are powerful tools of characterization for investigation of physical phenomena (e.g. electroanalytical technics, conductimetry, impedance meter, sensors etc.).
The core of the electrochemical cells is the electrochemistry. Furthermore, the electrokinetitcs at the surface reaction involves charge and mass transfer and it depends largely on the operating conditions. The performance of the electrochemical reaction requires the control of all the phenomena involved. Many physical processes have a strong impact on the behavior and performance of electrochemical devices. Whether it is the nature of the electrolyte (solid, liquid, flowing, multiphase) or electrode structure (porous, architectured materials) or the combination with other physical phenomena (thermal, magnetic).
Relevant approach to design and optimize the electrochemical devices is multiphysic approach. Our group adopts this approach to study electrochemical devices from a fundamental point of view and in different industrial applications.
Among issues addressed in this framework are:
• Electrochemistry and Magnetic Field
• Multiphase Flow in electrochemical cell
• Modeling tools for characterisation and design
