Water electrolysis is the most reliable hydrogen production method that captures hydrogen bubbles generated from electrochemical reactions. The generated bubbles are energy carriers and insulators and have a significant impact on water electrolysis efficiency. For a more practical quantitative evaluation of water electrolysis performance, continuous bubble nucleation-growth-escape behavior must be considered, similar to pool boiling.

In this paper, we develop a numerical model that simultaneously considers phase change heat transfer and hydrogen gas diffusion, and develop an expanded cyclic computation numerical model that includes cyclic bubble growth-escape behavior for the first time.
