Lattice Boltzmann Simulation for invasion processes during water electrolysis.
Among the critical challenges of the 21st century, providing sufficient and clean energy for a growing population while coping with the difficulties of global warming is still a struggle to the scientific community. Thus, transforming renewable energy to most reliable form of energy, electrochemical energy conversion is more promising technology. Therefore, water electrolysis is a major technology in demand for future sustainable development and the efficient hydrogen production is a potential substitute to the energy economy as hydrogen economy.
Here, we elucidate the invasion pattern of O2 gas evolving during the electrochemical splitting of water and mass transport losses in the anodic porous transport layer (PTL) using Lattice Boltzmann model (LBM). LBM is a mesoscale approach which plays as an interface by solving the Navier-Stokes equation at macroscale and imitate the pseudopotential intermolecular forces at microscale. Validation experiments will be provided to further to track the invasion patterns and renders LBM as a powerful multiphase CFD tool for intricate application of electrolysis in PTL.
