中性子を活用した非白金系燃料電池触媒の開発

抄録

As an example for industrial applications of neutron techniques, we report the result of our catalytically-active-site analysis with powder neutron diffraction for tantalum-oxide-based oxygen reduction electrocatalysts, which are expected to be used for future fuel-cell powered vehicles. Owing to the higher sensitivity of neutrons to oxygen, we were able to specify the possible active sites of the catalysts, which consist of oxygen-vacancy structural defects.
