“…Consequently, in order to gain insights into the proton ingress process, we constructed a COF/water interface model, as depicted in Figure 3. ReaxFF MD simulations were performed and the corresponding energy profiles for proton penetration were estimated using 75 G RT ln Z = (4) where ΔG stands for the free energy, R represents the ideal gas constant, T denotes the temperature (300 K), and ρ Z is the probability of proton occurrence at a distance z from the COFs. As illustrated in Figure 9 and Figure S16, both TpPa and TpPa-SO 3 H exhibit effective wetting by water, thereby ensuring uninterrupted continuity of the HB network during proton transport across the membrane.…”

“…The depletion of fossil fuels and growing global environmental concerns have prompted a widespread quest for alternative energy. , Fuel cell technology has emerged as a pivotal solution to address both energy and environmental challenges. Fuel cells, particularly proton exchange membrane fuel cells (PEMFCs), offer numerous advantages over conventional batteries, including enhanced energy conversion efficiency, reduced maintenance costs, and minimal environmental impact. − Proton exchange membranes (PEMs) serve as crucial components within PEMFCs, facilitating proton transportation while preventing the crossover of other species. Nafion, a perfluorosulfonic acid membrane developed by DuPont, remains the most commonly employed PEM. − However, its exorbitant cost and performance deterioration under high temperatures and low humidity pose limitations to its further adoption. − …”

The inherent porosity of covalent organic frameworks (COFs) establishes 1D conduits capable of facilitating swift proton transport while effectively impeding the passage of other species. This characteristic positions them as a promising avenue for engineering advanced proton exchange membranes in the future. However, the precise manner in which the structural attributes of the COF materials facilitate the proton transportation process remains enigmatic. This study delves into the intricacies of the proton transport mechanism within COFs, using the β-ketoenamine-based COFs TpPa and TpPa-SO 3 H as exemplars. By employing ab initio molecular dynamics and reactive force field molecular dynamics simulations, we elucidate the process. Our findings unveil that confined within the pore channels, protons showcase remarkable conductivity, primarily due to the establishment of a hydrogen bond network involving adsorbed water molecules and the COF surface structure. This interaction leads to conductivity levels as impressive as 10 −1 S/cm. Various factors, including humidity levels, functional group decoration, and stacking arrangements, exert varying degrees of influence on the proton conduction process. Moreover, at the interface between the COF and water, the presence of sulfonic acid functional groups significantly reduces the free energy barrier for proton ingress into the pore channels, thereby contributing to the heightened proton conductivity observed in experimental settings. These unveiled transport mechanisms and influencing factors hold promise for guiding the selection and design of proton exchange membranes with exceptional performance.

“…23 Nonetheless, this type of fuel cell has significant challenges, mainly it employs an expensive catalyst (platinum). 24 Thus, to address these limitations, an anion exchange membrane (AEM) can be employed, considering its advantage that it avoids the use of expensive metal catalysts. Moreover, this approach reduces the severe corrosion under alkaline conditions due to the counter-direction between the fuel and OH ions.…”
