چکیده انگلیسی
In this paper, well decorated PdCe bimetallic on carbon nanofibers were synthesized by the cost effective electrospinning process and effectively applied as electro-catalyst for the detection of methanol fuel cells (MFCs). The synthesized PdCe bimetallic decorated carbon nanofibers were characterized in details using morphological, crystalline, structural, surface and electrochemical techniques. The crystalline and structural properties expressed the formation of PdCe alloys on the surface of carbon nanofibers during the electrospinning process. The PdCe bimetallic decorated carbon nanofibers were used to construct the effective anode for the high performance DMFCs and the cell performance evaluated by electrochemical measurements such as cyclovoltametry and electrochemical impedance. The PdCe bimetallic decorated carbon nanofibers based electrode presented the reasonable performance toward the methanol oxidation as increasing the current density with the increase of methanol concentration in alkaline medium. The addition of methanol in alkaline medium significantly increased the current density, which suggests that PdCe bimetallic decorated carbon nanofibers based electrode have excellent electrocatalytic activity towards the methanol.
