Data Content: This dataset covers SEM images, graphitization degree, pore size distribution data, as well as gas permeability, contact resistance, tensile strength, flexural strength and other relevant data generated during the research on carbon paper and gas diffusion layers.
Collection Scheme: A series of carbon papers with gradient pore structures and gas diffusion layers with different component compositions (carbon black, graphite flakes, carbon nanotubes) were prepared. Different samples were sent to the State Engineering Research Center for Powder Metallurgy Laboratory of Central South University for analysis and testing, including SEM images, graphitization degree, pore size distribution, gas permeability, contact resistance and mechanical property data. Third-party testing of carbon paper and gas diffusion layer samples was entrusted to Dongguan Xinzhun Testing Technology Service Co., Ltd. for testing, mainly detecting gas permeability, bulk density, porosity, tensile strength, flexural strength, vertical resistivity, surface resistivity and other data.
