This paper proposed a pore scale analysis model of mass transfer and chemical reaction in the positive pole. The lattice Boltzmann method was used to simulate the steady-state reaction process under the condition of constant current charge. The distribution of the concentration of liquid phase reaction ions, the proton concentration of the solid phase and the density of the reaction current were obtained. The influence of electrolyte flow velocity and charge current density on the electrode reaction was further explored.
