제목 Effects of phosphoric acid on alloy catalyst for oxygen reduction reaction in high temperature polymer electrolyte fuel cell
초록 In high temperature polymer electrolyte membrane fuel cell (PEMFC), phosphoric acid in the polymer membrane can leak out, and catalyst surfaces in the electrodes may be poisoned by phosphoric acid anion adsorption. Especially, catalysts in the cathode are significantly affected by specific anion adsorption due to sluggish oxygen reduction reaction (ORR) activity. The effects of phosphoric acid on the alloy catalysts in the cathode were investigated by electrochemical analysis. In additon, the dependence of specific anion adsorption on the electronic structures of alloy catalysts was studied.
