A non-thermal plasma cell containing cyclic product ( 2 ) of an insulating material formed from a continuous wall materials ( such as ceramic ) , the continuous wall is annular having a plurality of openings ( 10 ) and ( 2 ) , a pair of annular air electrode attached to both sides of the wall of the insulator , if necessary , an air gap is provided between each electrode and the wall on at least a portion of the periphery of the wall non-thermal plasma cell having a . The thickness of the insulating material is substantially greater than the thickness of the electrode may include a metal foil. .. [ Selection Figure Figure 6 .材料の連続壁から形成された絶縁材料(セラミックなど)の環状物(2)を含む非熱プラズマセルであって、前記連続壁が、複数の開口(10)を有する環状物(2)と、前記絶縁体の前記壁の両側に取り付けられた1対の環状通気性電極と、必要に応じて、前記壁の前記周囲の少なくとも一部分上の各電極と壁との間に提供された空気ギャップとを有する非熱プラズマセル。絶縁材料の厚さは、金属箔を含むことがある電極の厚さより実質的に大きい。【選択図】図6
