Simulation of single and multiphase (bubbly) flows through 3-D porous electrodes for green hydrogen production
Green hydrogen production based on water electrolysis powered by renewable electricity is gaining increasing interest and significance in our attempts to evolve towards climate neutrality. In an attempt to increase the efficiency of today's water electrolysers, i.e. increase the hydrogen production rate at fixed electrical power, the use of high surface 3-D porous electrodes in a so-called zero-gap cell stack configuration has turned out to be an appealing technological option. However, such electrodes pose new challenges in the evacuation of the generated gas bubbles. Recent research in our team has demonstrated the potential of using either commercially available open-cell foams [1] or specific 3-D printed structures [2] tailored towards enhanced bubble removal.
In the framework of a recently approved European project, including 2 industrial and 3 academic partners, we would like to extend our activities in the field by intensifying our CFD expertise towards simulation of multiphase (bubbly) flow through such 3-D porous electrodes. The specific workpackages of the project include
Experience and solid track record in one of the above research fields is a must.
Expected starting date : between 01/03 and 01/09/2024
