Abstract


The study of scattering dynamics in thermal environments around Proton Exchange Membrane Fuel Cell (PEMFC) electrode is crucial for understanding the behavior of charge carriers and the impact of thermal gradients on fuel cell performance. The aim of this work is to develop theoretical model of the Differential Cross Section (DCS) around the anode of PEMFC, focusing on electron interactions within thermal environment generated during H2/Pt reactions. The developed theoretical model, explores the DCS dynamics under varied parameters such as scattering angles, incident electron energies, separation distances between target and incident electrons, considering both temperature effects and their absence. The findings unveil intricate DCS patterns across diverse conditions, offering significant insights into PEMFC efficiency and performance. On comparisons across three polarization scenarios reveal distinctive DCS trends, with linear polarization exhibiting lower values compared to circular, and circular polarization lower than elliptical, concerning scattering angle, energy, and distance separation. Moreover, the study investigates the interplay between DCS and PEMFC current production, the interaction between quantum species formation around electrode resultant output current. The computed of model highlight the influence of interaction surface size, charge analysis, and electrode current density on DCS behavior, providing pathways for optimizing PEMFC performance. Additionally, the study examines temperature variations within PEMFC in relation to current density and surface area. The results underscore complex relationships between these factors, emphasizing their implications for thermal management strategies in PEMFC design. Overall, this study offers comprehensive insights into the intricate dynamics of DCS within PEMFC, furnishing valuable guidance for enhancing PEMFC efficiency and performance across diverse operational contexts.
