Abstract
Disclosed is a method for fabricating a multilayer-structured exhaust gas decontamination reactor. The method comprises the following steps: (1) fabricating a plurality of electrochemical-catalytic conversion units, (2) providing spaced filtering areas for loading the electrochemical-catalytic conversion units and front and rear filter boards of a plurality of hollowed interconnection regions , (3) allowing the front filter board to be staggered from the rear filter board, and (4) respectively installing the front and rear filter boards at an input end and an output end of a frame body, so that the input end, the interconnection regions of the front and rear filter boards, and the output end jointly form a channel allowing the exhaust gas to flow. Thus, the electrochemical-catalytic conversion units of the invention are exposed to the channel to function as the reaction sides for decontaminating the exhaust gas. An additional reducing gas system is not needed, so that the volume and lower production cost of the exhaust gas decontamination reactor are reduced.
