Polymer electrolyte fuel cells are attracting attention as a renewable energy device. While CNWs consist of multilayer graphene sheets vertically standing on a substrate, it is expected to have good gas diffusion and conductivity. However, resistance polarization and diffusion polarization of CNWs are not elucidated yet. In this study, we have clarified polarization characteristics of CNWs with different density by impedance analysis.
