Among such renewable energy, hydrogen is used as an energy carrier in the fuel cell. Among diﬀerent fuel cell types, the high-temperature proton exchange membrane fuel cell (HT-PEMFC) has attracted many researchers due to its wide variety of applications. HT-PEMFC must be further studied to enhance its performance and durability to meet the energy requirements. In the present study, a three-dimensional non-isothermal model is developed to numerically investigate the durability and performance of a HT-PEMFC. The developed model is validated against the experimental data available in literature. A spatial characterization of CO poisoning in HT-PEMFC is carried out to investigate the spatial resolution of the polarization curves, H2 concentration, current density, and anode polarization loss. A graded cathode catalyst structure is studied to enhance the oxygen reduction reaction. The study reveals that the multiple graded CLs improve performance but leads to uneven current distribution, and high Pt loading downstream signifcantly improves uniformity in the current distribution. The study also proposes a hybrid catalyst structure to enhance performance and current distribution. The eﬀect of various degrees of misalignment of ﬂow feld plates and its concomitant impact with varying the clamping pressures on HT-PEMFC operation is investigated to analyze the electrochemical behavior, reactant distribution, heat transport, electric transport, and cell performance and also suggests the allowable misalignment tolerance. The proton conductivity numerical model for cage-like cross-linked membranes for enhanced proton conductivity in HT-PEMFC is developed to give a detailed and fundamental understanding of the polarization phenomena and species transport. Sensitivity analysis of operational parameters of HT-PEMFC is carried out to investigate the inﬂuential sensitivities of crucial operating parameters on evaluation index such as cell voltage, a standard deviation of current density distribution, a mean and standard deviation of overpotentials of anode and cathode at diﬀerent operating current density regimes. The present research explores the possible improvement and enhancement in cell performance and uniform species distribution to enhance cell performance and durability.
