Sandwich-like Nafion composite membrane with ultrathin ceria barriers for durable fuel cells

Yun Sik Kang et al.

Summary: Improving the durability of PEMFCs by incorporating radical scavengers such as ceria into the MEA, especially the membrane, is crucial for further commercializing polymer electrolyte membrane fuel cells. A novel method of constructing a robust membrane by adding ultrathin ceria barriers to the outermost sides of a commercial Nafion membrane has been developed, leading to enhanced durability and proper areal density of CeO2 barriers. The decreased amount of fluoride ion emission and loss of proton conductivity with increasing CeO2 density suggest improved performance and durability of the modified membrane.

Mechanical stress and strain investigation of sulfonated Poly(ether ether ketone) proton exchange membrane in fuel cells: A numerical study

Mehran Yousefi Tehrani et al.

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.

Current status of cross-linking and blending approaches for durability improvement of hydrocarbon-based fuel cell membranes

Seyed Hesam Mirfarsi et al.

Summary: Due to the demand for reliable and economical fuel cells, researchers have focused on improving the durability of hydrocarbon-based proton exchange membranes (PEMs) without compromising performance. Cross-linking and blending techniques show promising potential in creating a 3D network within the membrane structure, resulting in improved long-term stability and durability. These membranes have demonstrated over 4000 hours of durability in hydrogen fuel cells and significantly lower methanol crossover compared to conventional fluorinated membranes, indicating their potential for commercialization.

A review of alternative polymer electrolyte membrane for fuel cell application based on sulfonated poly(ether ether ketone)

Nur Ain Masleeza Harun et al.

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.
