| Outline of Final Research Achievements |
In the present technology, a small-sized all-solid-state sensor is installed in the exhaust manifold of a diesel vehicle to instantly measure the PM concentration in the exhaust gas. Specifically, an electrochemical device, consisting of a proton conducting electrolyte and an electrode catalyst, is operated through the following processes: (1) active oxygen species are electrochemically produced in the exhaust gas; (2) the PM is oxidized by the active oxygen with 100% efficiency; (3) a large electrical signal is generated in the process of (2). This sensor enables continuous monitoring of PM, which is not possible for sensors reported so far, because it has self-regeneration ability.
