- 排気ガス中の粒子状物質を浄化するためのプラズマ反応器用電極であって、
排気ガスが流通する経路上におけるプラズマ放電を行う空間に配置され、粒子状物質を含む排気ガスを通過させる孔を有した多孔質のニッケル又は銅からなり、
2枚の当該電極を誘電体を挟んで対向配置する場合において、
前記誘電体により2枚の当該電極間の距離がプラズマを発生させるのに十分な大きさに保たれるとともに、排気ガスは誘電体の内部を通過せず、
当該電極が有している前記孔は、その内壁間において、またはその内壁に有する凹凸形状の凹部分において、排気ガスに含まれる粒子状物質を捕捉するが、排気ガス自体は当該電極における前記誘電体とは反対の面側から誘電体の方を向く面側まで通過させることができるものであり、
排気ガスが当該電極を通過し当該電極と前記誘電体との隙間を介して下流側へと移動するプラズマ反応器用電極。 - 排気ガス中の粒子状物質を浄化するためのプラズマ反応器用電極であって、
排気ガスが流通する経路上におけるプラズマ放電を行う空間に配置され、粒子状物質を含む排気ガスを通過させる孔を有した多孔質のニッケル又は銅からなり、
前記孔は、その内壁間において、またはその内壁に有する凹凸形状の凹部分において、排気ガスに含まれる粒子状物質を捕捉するが、排気ガス自体は通過させることができるものであり、
前記孔の開口が閉塞されないように、また前記孔が粒子状物質を捕捉するのに十分な内部寸法を確保して、誘電体をコーティングしてあり、
対をなす当該電極がプラズマ放電を開始し得る距離をあけて配置され、プラズマが発生するその電極間の空間に排気ガスが流入するプラズマ反応器用電極。
