Researchers at Chalmers University of Technology in Sweden have made significant progress towards improving fuel cell technology for hydrogen-powered vehicles. The study focuses on understanding the degradation of fuel cell components over time, which has been a limiting factor in the lifespan and efficiency of fuel cells. By developing a new method that allows for tracking specific particles within the fuel cells, researchers can now identify and study degradation at both nano and micro levels. This method provides crucial insights for enhancing the performance and durability of fuel cells, a necessary step for the commercial viability of hydrogen-powered heavy-duty vehicles. The U.S. Department of Energy has highlighted the need to extend the lifetime of fuel cells to make hydrogen-powered vehicles commercially successful. Currently, fuel cell-powered trucks struggle to meet the required lifespan of 20,000-30,000 hours of driving. This research at Chalmers University of Technology addresses this challenge by laying the foundation for developing new materials that can significantly improve the lifespan of fuel cells. The research team, led by Associate Professor Björn Wickman and doctoral student Linnéa Strandberg, has published their findings in several scientific articles, showcasing the impact of their innovative method in studying fuel cell degradation. The project, supported by Swedish research organizations and industry partners, signifies a crucial advancement in fuel cell technology, essential for the future of sustainable transportation. This research not only contributes to the scientific understanding of fuel cell behavior but also offers practical solutions for designing more efficient and longer-lasting fuel cells, ultimately shaping the future of hydrogen-powered vehicles.
