摘要：

3M's Nanostructured Thin Film (NSTF) electrode offers an alternative path to reduce Pt cost in a polymer electrolyte membrane fuel cell, owing to its unique extended surface structure. To understand the fuel cell performance and the durability of the electrode, it is necessary to know its microstructure. In this report, electrochemical and microstructural evaluations of the NSTF electrodes were done after different stages of ageing in a fuel cell. Changes over time of surface roughness, dealloying, and microstructure were observed. Correlations between NSTF electrode structure and fuel cell performance are discussed.
