Influence of vanillic acid immobilization in Nafion membranes on intramembrane diffusion and structural properties

Blake Trusty et al.

Summary: PFG NMR and QENS techniques were used to study the self-diffusion of water and acetone in Nafion membranes with and without immobilized VA. The results showed that the addition of VA did not significantly affect the self-diffusivity of water and acetone within the micrometer-sized domains of Nafion. However, the presence of different acetone concentrations in membranes with and without VA had different effects on the water permeance of the interfaces between neighboring domains. These diffusion data were correlated with structural characterization and NMR relaxation data.

Silicone-containing polymer blend electrolyte membranes for fuel cell applications

Byungchan Hwang et al.

Summary: Polymer electrolyte membranes are developed from blends of Si-Epoxy and SPI, with comparable mechanical strength to Nafion 211 but better resistance to deformation. The higher chemical durability and proton conductivity of the membranes are attributed to the formation of CT complexes and the sulfonic acid content in SPI.

Hydrocarbon-based Pemion™ proton exchange membrane fuel cells with state-of-the-art performance

Hien Nguyen et al.

Summary: Non-fluorinated hydrocarbon ionomers offer technical, cost, and environmental advantages over perfluorinated sulfonic acid-based ionomers, but their performance in hydrogen fuel cells still needs improvement. The study presented in this paper demonstrates significant enhancements in power density and performance by using a sulfo-phenylated polyphenylene-based cation exchange material as ionomer in the catalyst layer and proton exchange membrane.
