Abstract

hydrogen molecular ions polarization states proton-exchange membrane fuel cells scattering dynamics thermal Volkov wavefunction
The scattering characteristics of electrons at the surface of proton-exchange membrane fuel cells (PEMFCs) have implications in their operating efficiency and thermal stability, especially in presence of hydrogen molecular ions (H2+). The aim of this work is to study the differential cross sections (DCSs) with respect to laser field strength, polarization, temperature, thermal conductivity, and electron momentum. To develope the model, a thermal Volkov wavefunction was applied, which meet the condition at surface of PEMFC electrode due to finite motion of the electrons and exothermic reactions. The transition matrix was constructed using H2+ potential while the probability calculations were carried out for different orbital quantum numbers, exciting field polarization states, as well as laser intensities. The calculated results show that DCS generally increases with field strength, temperature, and angular momentum quantum number except for polarization and variation of the transferred momentum which affect stability and magnitude of scattering. Also, an increase in the field intensity causes more scattering while that in thermal conductivity intensified electron–field coupling, which leads to an enhancement of DCS. In addition, the plateau regions at DCS in higher momentum or cell voltage indicate a stable scattering zone under PEMFC operation. Higher DCS is obtained for linear polarization compared with circular and elliptical, which result in lower and more constant scattering. The resulting theoretical framework relates microscopic electron–ion interactions to macroscopic fuel cell efficiency and durability, providing guidance for the development and optimization of membrane–proton exchange fuel cells that can combat wide variations in operational conditions.
