Abstract
A new measurement method is suggested to quantify the phosphate poisoning of cathodic Pt catalyst for HT-PEMFC. To do that, hydrogen peroxide was used as an indicator to reduce the error which has been occurred in conventional electrochemical measurement such as CV or ORR RDE with high concentration of phosphate ions. As a result, the current density induced from the reaction of hydrogen peroxide decomposition increased proportionally to the concentration of phosphate ion while the conventional methods show has a significant error with high concentration of phosphate ion. Thus, it is confirmed that the suggested way is superior to the conventional measurement method for the quantification of phosphate ion poisoning in an atmosphere similar to the actual operation condition of HT-PEMFC.
