Abstract
【解決手段】浄化装置20は、O2−を伝導するO2−伝導部31と電子を伝導する電子伝導部32とを有するイオン電子伝導層21と、そのイオン電子伝導層21の一方側の第1面に、粒子状炭素質物質(PM)を酸化するPM酸化層22と、イオン電子伝導層21の第1面とは反対の他方側の第2面に、NOxを還元するNOx還元層23とを含んで構成される。イオン電子伝導層21のO2−伝導部31は、PM酸化層22の電子をNOx還元層23へと伝達する。また、イオン電子伝導層21の電子伝導部32は、NOx還元層23のO2−をPM酸化層22へと伝達する。PM酸化層22側で、PMをCO2へ変換し、NOx還元層23で、NOxを還元する。
