Coupling Mechanism of Electrical Double Layer and Mass Transport for Bubble Nucleation at Electrode Interfaces by Jiaxuan HU, Changqing GUO, Zhida WANG, Yan SHI, Lisha SHEN, Hongyu HUANG, Changfeng YAN

“…During the process of water electrolysis,the "bubble effect" will significantly reduce the overall performance of the system.The classical nucleation theory (CNT model） fails to reveal the regulatory mechanism of the electrical double layer (EDL),surface microstructure,and mass transfer synergy on nucleation kinetics in actual electrochemical systems.This study develops an electrode interface bubble nucleation model with the synergistic effect of electrical double layer⁃mass transfer⁃surface microstructure,considering the synergistic regulation mechanism of ion migration diffusion behavior,electrode surface nano microstructure,and concentration boundary layer on the nucleation process.The research results show that the synergistic effect of EDL and microporous structurel generates significant potential gradients at the surface micropores,leading to an increase in local supersaturation and prioritizing bubble nucleation.At high overpotentials,the effect of the concentration boundary layer on nucleation energy barrier exhibits a nonlinear relationship.The thinner the concentration boundary layer is,the more significant the decreasing trend of the nucleation rate at high potential will be.The growth of bubbles is dominated by the net concentration flux near the three⁃phase contact line (TPCL),exhibiting a two⁃stage growth characteristic.The study provides a theoretical basis for optimizing the surface design of gas evolution electrodes.…”
