Investigation on the variation law of gas liquid solid three phase boundary in porous gas diffusion electrode [PDF]

Heliyon, 2018
The three-phase boundary length will change with the electrochemical reaction in the working process of the gas diffusion electrode. The process of porous media fluid interface movement is investigated by establishing the physical and mathematical model ...
