OXYGEN REDUCTION REACTION IN THE PRESENCE OF METHANOL USING CoFeRu ELECTROCATALYST

A. Sandoval Gonz Lez, E. Borja Arco

Abstract :

<p> Investigations in direct methanol fuel cell (DMFC) have increased the demand for fundamental information about the behavior of the cathode electrocatalyst. Typically electrocatalyst (Pt) used for the oxygen reduction is rapidly poisoned due to the methanol crossover effect. For this reason, it is necessary to search lower cost and long useful life time electrocatalyst. CoFeRu was synthesized by microwave method at 180°C for 30 minutes. SEM morphology showed agglomerates of particles of different size. The EDS analysis showed few atomic percentage elements content (Co, Fe, Ru). According to X–ray diffraction the trimetallic CoFeRu phase is not observed. Electrochemical characterization demonstrated that the electrocatalytic activity of CoFeRu toward ORR is not affected by the methanol presence (1 and 2 mol L–1). CoFeRu could be an excellent electrocatalyst as cathode in DMFC.</p>
