Summary: A novel proton exchange membrane fuel cell/engine based cogeneration system with methanol fuel (MPEC system) for ship application is proposed in this study. The MPEC system utilizes an online catalytic reforming process to obtain hydrogen from methanol fuel, which significantly improves the generation efficiency by 19.55% compared to a single engine. The comprehensive performance analysis shows that the MPEC system achieves high cogeneration efficiency and power generation efficiency of 81.84% and 50.46%, respectively, with a total life cycle carbon emission of 344.938 g/kWh and a levelized cost of energy of 0.1411 $/kWh.

Summary: In this study, a system combining PEMFC and ORC is analyzed using thermodynamic modeling and advanced exergy analysis. The results show that the exergy destruction rate in the PEMFC stack is the highest among the components. The PEM fuel cell exergy efficiency is 46.89% while the overall electrical efficiencies are 39.06% and 44.81% for the fuel cell and the system, respectively. The study also reveals that the compressor has poor performance and a large portion of its exergy destruction is unavoidable. Furthermore, a parametric study shows that increasing the current density can improve the overall efficiency of the system.

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: Coating a reinforced composite membrane with a hydrophilic Pt layer improves the durability of polymer membranes used in fuel cell applications. A Pt coating was introduced onto the composite membrane, resulting in increased hydrophilicity and better performance. The Pt-coated composite membrane showed less degradation and lower fluorine emission rate, making it a potential candidate for proton exchange membrane fuel cells.

Summary: In this study, a novel approach for preparing membrane electrode assemblies (MEAs) is proposed to optimize the interface combination and durability of proton exchange membrane (PEM) and catalyst layers (CLs). This approach combines a wet-contact interface design strategy and expanded polytetrafluoroethylene (ePTFE) reinforcing technology. The MEAs prepared using the wet-contact process show significantly reduced interfacial resistance and charge-transfer resistance, improved electrochemical surface area, and superior power performance compared to conventional MEAs. The insertion of ePTFE reinforcement skeletons into the PFSA membrane also reduces hydrogen crossover and mechanical degradation.
