磷酸浓度与温度对Pt/C催化氧还原反应的影响
Effect of H3PO4 concentration and temperature on Pt/C catalyzing ORR
摘要
Abstract
The effect of H3PO4 concentration and temperature on Pt/C catalytic oxygen reduction reaction (ORR) in high temperature proton exchange membrane fuel cell was studied by rotating disk electrode method.The ORR kinetic current density and diffusion limited current of Pt/C catalyst decreased with the increase of H3PO4 concentration,when the concentration increased to 100％,the current density nearly decreased to 0.The current increased when the temperature increased,but the increment was not more enough to meet the needs of practical application.The increasing of H3 PO4 concentration had a great inhibition effect on ORR of Pt/C catalyst,while the effect of temperature changing was limited.关键词
