What is it about?
Polybenzimidazole (PBI) is used in high temperature proton exchange membrane fuel cells (HT-PEMFCs) and redox flow batteries, where proton transfer occurs with the nitrogen-containing groups in PBI, and in aerospace application where it is exposed to oxygen and radiation. Therefore, this research investigated Vacuum UV (VUV) photo-oxidation of PBI.

Why is it important?
The importance of this research was to Incorporate polar function groups on the surface of PBI and potentially enhance the proton conductivity and increase the performance of HT-PEMFCs.
Perspectives
VUV photo-oxidation was shown to be an effective technique for oxidizing the surface of PBI and increasing hydrophilicity.
