A research team led by Dr. Chi-Young Jung at the Hydrogen Research and Demonstration Center, Korea Institute of Energy Research (KIER), has made significant strides in the analysis of carbon fibre paper, a crucial element in hydrogen fuel cell stacks. By leveraging digital twin technology and artificial intelligence (AI), the team developed a methodology that accelerates microstructure analysis by 100 times compared to conventional techniques. This breakthrough allows for prompt condition assessment in hydrogen fuel cell components without relying on electron microscopy, enhancing efficiency and accuracy. Through the utilization of X-ray tomography and AI-based image learning, the researchers extracted and analyzed 5,000 images from a vast sample pool, training the AI model to accurately predict the 3D distribution and arrangement of carbon fibre paper constituents. Achieving an impressive accuracy rate of over 98%, this innovation signifies a significant leap in material analysis techniques. Dr. Jung emphasized the practical implications of this advancement, foreseeing its applicability not only in hydrogen fuel cells but also in diverse fields like secondary batteries and water electrolysis. The study, published in the journal Applied Energy, underscores the potential of AI-driven analytical tools to revolutionize energy material research and development.
