Abstract
A non-thermal plasma reactor element is provided comprising a multi-cell stack prepared from a plurality of formed building blocks of dielectric material, the walls of the building blocks defining a cell having an exhaust passage for flowing gas to be treated therethrough. A conductive print forming an electrode and connector is disposed on at least one wall of each of the cells and outer insulative plates, disposed on opposite ends of the multi-cell stack, are provided to protect the conductive print. The simplified design eliminates the need for spacers between individual cells, thus reducing the total number of components. Use of a three-dimensional conductive print further simplifies preparation by eliminating the need for a secondary conductive print along the edge of the multi-cell stack after assembly.
