摘要

Electrochemical experiments, including cyclic voltammetry (CV) experiments, galvanostatic experiments, potentiostatic experiments, and kinetic experiments of the LSM electrode, were used to investigate the influence of a deposit on the electrode surface on the electrophoresis of protons in a porous media during electrophoretic deposition (EPD). In the kinetic experiments, the deposit reduced the electrochemical reaction rate of the LSM electrode according to the Tafel plots for the cathode where the YSZ was deposited. It was also observed that hydrogen was reduced at the cathode from the cyclic voltammogram. In the galvanostatic experiments, the proton concentration increased near the cathode because the deposit obstructed the electrode reaction. In the potentiostatic experiments, similar phenomena were observed. The deposit from the EPD became an obstacle to the electrochemical reaction, resulting in unusual kinetic behaviors of proton electrophoresis during electrolysis.
