Interplay between structure and properties in acid-base blend PBI-based membranes for HT-PEM fuel cells

This work is the follow-up to a previous study in which the same authors extensively documented the behaviour of acid-base polymer blend membranes doped with phosphoric acid during high temperature (160 °C) fuel cell operation. The present study examines the same acid-base blend PBI-based materials to obtain a deeper understanding of the relationship between the chemical structure and the membrane properties, particularly in the presence of...
