Synthesis and Characterization of MnO2 as Electrocatalytic Energy Material for Fuel Cell Electrode
Abstract
Development Inexpensive non Pt based high electrocatalytic energy materials is the need of hour for fuel cell electrode to produce clean alternative green energy from synthesized Bio alcohol from Biomass. MnO2 electro synthesized at different current density is found to be well performed electrocatalytic material, comparable to Pt, with higher current density, very low over voltage for electrochemical oxidation of methanol . From EIS study, the polarization resistance of the coated MnO2 is found to be much low and electrical double layer capacitance is high, the effect increases with increase in current density of electro deposition. XRD , EDX and AAS analysis confirm the MnO2 deposition, the amount increases with current density. SEM morphology exhibits enhanced 3D effective substrate area for electro oxidation of the fuel and a few nano structured grains of deposited MnO2 at higher current density. The fact supports an improved electro catalytic property to be applied as high energetic materials for fuel cell Electrode.
