At the 248th Electrochemical Society Meeting, Florian Tritscher from Graz University of Technology presented his abstract titled:

“Real-world accelerated stress test protocol for high-temperature proton exchange membrane fuel cells based on heavy-duty vehicle operation.”

This abstact addresses a critical gap in hydrogen technology: the lack of standardized accelerated stress tests (ASTs) for high-temperature PEM fuel cells (HT-PEMFCs). These fuel cells are ideal for heavy-duty vehicles thanks to their ability to operate at higher temperatures, use lower-cost hydrogen, and require fewer heat exchangers compared to low-temperature systems.

Florian introduced a novel AST protocol that simulates real-world conditions using a multi-layered modeling framework and realistic drive cycle data from the Trans-European Transport Network. This protocol was tested over 100 hours on both state-of-the-art phosphoric acid-doped polybenzimidazole membranes and new ion-pair based membranes, aiming to overcome durability challenges like phosphoric acid leaching.

This research supports the development of standardized testing procedures, fostering collaboration between academia and industry to accelerate innovation in HT-PEMFCs for heavy-duty applications.

Congratulations to Florian for contributing to the advancement of clean mobility and setting new benchmarks for HT-PEMFC testing!
