Hydrogen as a fuel alternative has garnered attention for heavy-duty vehicles due to its emissions-free nature and potential for carbon neutrality when produced from renewable sources. Unlike electric vehicles dependent on the grid, hydrogen-powered vehicles can produce and store hydrogen during off-peak periods. However, the lifespan of hydrogen fuel cells, particularly those in fuel-cell-powered vehicles, has been a limitation due to component degradation, impacting their efficiency. Researchers at Chalmers University of Technology in Gothenburg have made strides in addressing this challenge by developing a new method to study fuel cell ageing. By disassembling and tracking specific particles within fuel cells using advanced electron microscopes, they can pinpoint degradation at both nano and micro levels. This innovative approach provides valuable insights for enhancing fuel cell longevity and efficiency, contradicting previous assumptions about the effects of disassembly on performance. The study's detailed analysis offers a crucial understanding of the degradation processes, essential for designing new materials and optimizing fuel cell control. This research marks a significant step forward in advancing fuel cell technology for sustainable transportation solutions.
