Data content: Polarization curves, cyclic voltammetry (CV) curves and scanning electron microscopy (SEM) images of fuel cells under hydrogen-oxygen and hydrogen-air conditions generated during the optimization of catalyst inks. Also included are simulated calculation models, radial distribution function (RDF), mean squared displacement (MSD), radius of gyration (Rg) and cluster distribution data, etc.
Collection scheme: Scanning electron microscopy (SEM) images, transmission electron microscopy (TEM) images and X-ray photoelectron spectroscopy (XPS) data of catalyst layers following the interaction between cyclohexanol and Nafion ionomer were characterized (measured at the Analysis and Testing Center of Chongqing University). Additionally, polarization curves of membrane electrode assemblies (MEAs) prepared from the optimized catalyst inks were measured using a full-featured fuel cell testing system under hydrogen-oxygen and hydrogen-air conditions. For theoretical simulations, molecular dynamics simulations were conducted on a supercomputer platform.
