Journal of Electrochemistry

A high performance membrane electrode assembly (MEA) with low platinum loadings was successfully prepared with atomic layer deposition (ALD) technique. The anode of the MEA was prepared by depositing platinum on the carbon paper substrate, which was prepared by coating the slurry of carbon black (XC-72R) and Teflon, followed by drying and calcining at 350 °C. The MEAs consisted of the ALD anode or commercial catalyst anode, pretreated Nafion membrane (Nafion-117) and commercial cathode. Performances of MEAs were measured by single cell testing, and the anodes and MEAs were characterized by CV, SEM, TEM and XRD. The results revealed that …
