Ionomer distribution control via thiophene S-modification of carbon support for high-power proton exchange membrane fuel cells

This dataset contains the source data underlying all findings reported in this manuscript and its Supplementary Information. The data are organized into several parts: Source Data for Figures: This includes all numerical data used to generate the plots, charts, and graphs in the main text and supplementary figures. Data for each figure are compiled in a single Microsoft Excel (.xlsx) file, with individual sheets named according to the corresponding figure and panel (e.g., 'Figure_1a', 'Figure_S3b'). Computational Data: This section contains the key output files, and processed data from the Density Functional Theory (DFT) and Molecular Dynamics (MD) simulations conducted in this study.
