Proton exchange membrane fuel cells (PEMFCs) are being developed as alternative energy sources for both residential and automotive applications. For this technology to reach its full commercial potential, a significant reduction in cost is still required while the performance and durability of PEMFCs must be maintained or improved. In recent years, several microscopy techniques have become widely available to characterize the three-dimensional structure of PEMFC catalyst layers. By combining 3D imaging data at multiple scales, a unified structural characterization workflow and up-scaling approach has been developed enabling our client to make effective, predictive changes to their product.
