Abstract
A catalytic activity in an electric field was researched for further lower cost and more compact exhaust gas control system of plug-in hybrid electric vehicle than electrically heated catalyst system. Firstly, an experimental equipment and test protocol for an electric field was constructed. Secondly, it was confirmed that the catalytic activity in an electric field with palladium-ceria-zirconia complex oxide catalyst was occurred in the low temperature range where the conventional catalytic reaction was inactive. Finally, it was found that the catalytic activity in an electric field could be optimized by the catalyst specifications and the electric current.
