Preparation and Electrochemical Properties of Porous Platinum Electrode
Porous platinum electrodes were prepared by adding YSZ, as an active material, in platinum paste. Relationship between microstructure and electrochemical performance of O2(g), Pt/YSZ electrode have been characterized by SEM and cyclic voltammetry. Results showed that the microstructure of platinum electrode is a significant impact on the cyclic voltammetry. With the increase of platinum electrodes porosity, the area of three-phase boundary of O2(g)/Pt/YSZ was increased. The electrochemical reactivity was also enhanced. These were presented as the increase of current density and cathode voltage in cyclic voltammetry.
