Use of carbon nanocoil as catalyst support for development of high-performance fuel cell

When carbon nanocoils(CNCs) are used in fuel cell electrodes, the diffusion of fuel and gas, and the removal of reaction products, becomes considerably smoother. In this research project, I used CNC as an anode or cathode catalyst support material in direct methanol fuel cells(DMFCs). Other carbon nanoparticles, Arc-Black(AcB) and Vulcan, were also used as catalyst supports to compare with the CNCs. Compared with the catalyst layers of AcB and Vulcan, the catalyst layer of CNCs was confirmed to have several voids. As for the anode catalysts, the voltages of the PtRu/CNC and PtRu/Vulcan became almost the same at a high current density. As for the cathode catalysts, the power density of Pt/CNC was 1. 2 times higher than that of Pt/Vulcan and 1. 6 times higher than that of Pt/AcB. These results clearly show that CNC is a good catalyst support for fuel cell.
