Abstract
The performance of fuel cells depends on catalytic activity strongly. The interaction between catalytic activity and iron chelate (Fe-N-C) structure applying Rotating Ring-Disk Electrode (RRDE), evaluation of MEA performance, Hard X-ray Photoelectron Spectroscopy (HAXPES) and in-situ X-ray Absorption Spectroscopy (XAS). From the results of the investigations, it is confirmed that Fe is one of the active sites and find that the pyrrolic nitrogen structure enhances the catalytic activity.
