Summary: Improving the performance of proton exchange membranes (PEMs) through the synthesis of sulfonated polymers with elaborate molecular structures has been widely recognized. However, the complex synthesis process and high costs limit their substitution for Nafion. This study successfully prepared semi-crystalline sulfonated poly(ether ketone)s (SPEK-FD-x) with fluorene-based units via a facile synthetic pathway. The SPEK-FD-x membranes exhibited excellent proton conductivity, resistance to methanol permeation, as well as dimensional, thermal, oxidative, and mechanical stability, and even performed well in fuel cell applications. Therefore, the SPEK-FD-x membranes show great potential as an alternative to Nafion.

Summary: The effects of degree of branching and ion exchange capacity on the properties of sulfonated branched polymer proton exchange membranes (PEMs) were systematically compared. Increasing the degree of branching and ion exchange capacity improved water absorption, proton conductivity, single-cell performance, and distribution of hydrophilic phase, but reduced mechanical properties. Increasing the degree of branching also enhanced dimensional stability and oxidative stability, while the impact of ion exchange capacity was the opposite. The optimal polymer membrane had a degree of branching of 7.5% and ion exchange capacity of 1.94 meq g-1, exhibiting the highest proton conductivity and maximum power density, satisfactory dimensional change, and sufficient thermal, oxidative, and mechanical stability. This work serves as a guide for designing and synthesizing sulfonated branched polymer PEMs.

Summary: Prolonged hydrothermal treatment of sulfonated poly(ether ether ketone) membranes induces mechanical degradation and hydrophilic-hydrophobic phase separation, affecting proton conductivity and device stability. Aging processes through hydration-dehydration cycling and prolonged hydrothermal treatment lead to different changes in nanostructure and properties of the membranes. Fuel cell performance shows significant differences between the two aged membranes, with hydration-dehydration cycling leading to better durability.

Summary: SPEEK is recognized as a promising alternative PEM in fuel cell applications due to its advantageous properties, but its proton conductivity is influenced by the degree of sulfonation. While high DS of SPEEK can produce high proton conductivity, excessive production of DS may have side effects on membrane stability. Therefore, finding the optimal DS of SPEEK is crucial for fabricating PEM alternatives.

Summary: In this study, a complex finite element model is developed to investigate the mechanical response of hydrocarbon-based membranes under different fuel cell conditions. The results show that sulfonated poly(ether ether ketone) (SPEEK) membranes undergo the most severe swelling-induced degradation at low voltages, high temperatures, and backpressure values. Clamping pressure is a dominant factor, and Nafion membranes have a higher risk of wrinkle deformation under compression.

Summary: A dynamic model is developed to predict the concentration profiles of reactants, cross-over in the membrane, and hydrogen peroxide formation in a membrane electrode assembly (MEA) using sulfonated poly (ether ether ketone) (SPEEK) membrane. Results show that high voltages can accelerate the cross-over of reactants and promote the chemical mode of H2O2 formation. Additionally, reducing the membrane thickness increases the cross-over and formation of H2O2.

Summary: In the Resin Transfer Molding (RTM) process, a novel Dual-Scale Skeleton model (DSS) is introduced to solve the challenging task of simulating the dual-scale flow problem at an affordable computational cost. The DSS model replaces the three-dimensional geometry of a multi-layer layup with a skeletonized representation and uses a Reynolds-Darcy finite elements formulation to model the dual-scale flow. Numerical validation and application demonstration show that the DSS model is capable of simulating complex dual-scale flow problems at a reduced computational cost compared to full 3D solutions.
