A team of researchers in Seoul, South Korea, has developed an innovative approach to analyze the microstructure of carbon fiber paper, a vital component in hydrogen fuel cells. By leveraging digital twin technology and artificial intelligence (AI), the researchers achieved a speed 100 times faster than existing methods. Carbon fiber paper is essential in hydrogen fuel cell stacks for facilitating water discharge and fuel supply, composed of carbon fibers, binders, and coatings. Dr. Chi-Young Jung's team at the Korea Institute of Energy Research utilized X-ray diagnostics and an AI-based image learning model to analyze the microstructure. This technology eliminates the need for an electron microscope, enabling real-time condition diagnosis. Through training a machine learning algorithm with 5,000 images from 200 samples, the model accurately predicted the 3D distribution of key components with over 98% precision. Dr. Jung emphasized the significance of this study in enhancing analysis technology by merging AI with virtual space utilization, offering practical applicability in the energy material field. The research demonstrates the potential to impact areas like secondary batteries and water electrolysis in the future.
