Lattice Boltzmann Simulation for invasion processes during water electrolysis. 

Among the critical challenges of the 21^st 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.
