| Research Abstract |
In this study, we developed R-MnO2 catalyst that has higher activity for anode of the direct-DME fuel cell operated at intermediate-temperature. In order to investigate the mechanism how this catalyst makes a high activity, we applied both the a. c. impedance measurements and the inelastic neutron scattering. We found that the specific crystal structure of R-MnO2 (especially typical O-O bond length of R-MnO2) make the proton conductivity in the catalyst higher, and then the fuel cell performance is increased with this anodic catalyst.
