Optimizing operating conditions and stability evaluation of Fe/Co-NC catalyst in proton exchange membrane fuel cell.

ABSTRACT: Among all Metal-Organic Framework (MOF)-based catalysts, the bimetal structures perform more desirable in stability and output current density in the oxygen reduction reaction. Nonetheless, their stability in practical fuel cell systems and the influence of operational parameters on their performance remain unexplored to date. In the initial phase of this study, the electrochemical activity of a bimetallic metal-organic framework (MOF)-based cathode catalyst, specifically Fe/Co-NC(10 h), was investigated using three-electrode tests. Subsequently, the performance of catalyst (MEA2) was investigated under varying operating conditions within a single cell. Optimized operating conditions were then employed to assess the stability of the cathode catalyst through constant voltage and cyclic volt
