Generating the multifunctional influence by adding a promoter or employing a support for electrocatalytic particles is a remarkable approach to advance the efficiency and stability of anode electrode in the non-reforming methanol fuel cell. So, the coprecipitation assisted with ultrasonic is selected to fabricate porous LaMnO₃; and the nanosized Pd is loaded on LaMnO₃ via wetness incorporation. The samples are characterized through scanning electron microscopy, Fourier-transform infrared spectroscopy (FT-IR), vibrating sample magnetometry, Energy-dispersive X-ray spectroscopy (EDX), Transmission electron microscopy (TEM), Brunauer-Emmett-Teller and X-ray diffraction analysis. The electrochemical studies are carried out to identify the behavior and efficiency of electrocatalysts toward CH₃OH electrooxidation. Based on adsorption/desorption of hydrogen, the electrochemical surface area presented an ascending performance as nanosized Pd (76.63 m² g⁻¹) < Pd/LaMnO₃ (93.35 m² g⁻¹). The Pd/LaMnO₃ has higher electrocatalytic activity, stability, and CO-tolerance ability for the CH₃OH electrooxidation of as compared with nanosized Pd as non-supported Pd. The functions of current vs. time were determined by fitting and simulating of the experimental data. The transferred charge throughout CH₃OH electrooxidation vs. time was computed using the lower Riemann sum of plots, corresponding to experimental results and the integration of obtained functions. The introduced nanocomposite was used as anodic material in a single CH₃OH fuel cell.
