In this article, three different Fe-N-C oxygen reduction reaction (ORR) catalysts derived from different organic molecules i.e. Fe-NMG, Fe-NMP, Fe-MBZ have been synthesized, characterized by physical-chemical methods and studied in the reaction of oxygen reduction (ORR). It is found that Fe-NMG shows higher ORR performance than Fe-NMP and Fe-MBZ, by both rotating ring disk electrode (RRDE) and fuel cell tests. From characterization and surface analysis, it can be explained that the presence of higher amount of surface oxides and pyridinic nitrogen is the main reason for better performance towards ORR in alkaline media. To achieve the highest performance in alkaline exchange membrane fuel cell (AEMFC), the optimization of catalyst layer composition using various concentrations of ionomer (Tokuyama, AS4) was performed. At the optimum cathode layer configuration utilizing Fe-NMG produces the peak power density of 218 mWcm⁻², which is one of the highest values presented in the open literature.

本文通过物理化学方法对三种不同的Fe-NMG，Fe-NMP，Fe-MBZ等有机分子衍生的Fe-NC氧还原反应（ORR）催化剂进行了合成，并对其进行了研究。减少（ORR）。通过旋转环盘电极（RRDE）和燃料电池测试，发现Fe-NMG显示出比Fe-NMP和Fe-MBZ更高的ORR性能。通过表征和表面分析，可以解释为，在碱性介质中存在大量表面氧化物和吡啶氮是导致ORR性能更好的主要原因。为了在碱性交换膜燃料电池（AEMFC）中获得最高性能，使用各种浓度的离聚物（Tokuyama，AS4）进行了催化剂层组成的优化。^-2，这是公开文献中提出的最高值之​​一。
