文摘

Effects of bromomethane in air on PEMFC were studied with a segmented cell. Cathode exposure to 5 ppm CH3Br caused performance loss of 320 mV at 1 A cm−2. Hydrolysis of CH3Br resulted in formation of Br−. Br− and CH3Br negatively affected the ORR because of their strong adsorption on Pt. CH3Br exposure led to a significant decrease of anode and cathode ECA (∼52–57%).
