Based on the infiltration process in porous medium, with photographs of the gas diffusion electrode in electron microscope as an example, the real porous medium is grid-divided. With certain principles, the meshing porous medium is turned into topology network model, namely artificial assignment technology. And the infiltration process is simulated in porous medium with the low pressure condition.
