NOVELTY - Electrochemical-catalytic converter, which is used to control exhaust emission and generate electric power, comprises: (a) a cell module (10) further comprising a cathode compartment (11), an anode compartment (12) and a membrane-electrode assembly (13); (b) a heating unit embedded in the cell module; (c) a fuel input unit (50) and a fuel output unit (60); and (d) an exhaust gas input unit (30) and an exhaust gas output unit (40).    USE - The electrochemical-catalytic converter is used for controlling exhaust emission and generating electric power (claimed).    ADVANTAGE - The electrochemical-catalytic converter can remove nitrogen oxides, carbon monoxide, hydrocarbons, and particulate matter in exhaust gas and can generate electric power simultaneously.    DETAILED DESCRIPTION - Electrochemical-catalytic converter, which is used to control exhaust emission and generate electric power, comprises: (a) a cell module (10) further comprising a cathode compartment (11), an anode compartment (12), and a membrane-electrode assembly (13), where the membrane-electrode assembly is interposed between the cathode compartment and the anode compartment, and the cathode compartment includes an oxidation catalyst; (b) a heating unit embedded in the cell module; (c) a fuel input unit (50) and a fuel output unit (60) respectively coupled to two sides of the anode compartment to function as a fuel input terminal and a fuel output terminal of the cell module for operating; and (d) an exhaust gas input unit (30) and an exhaust gas output unit (40) respectively coupled to two sides of the cathode compartment to function as an exhaust gas input terminal and an exhaust gas output terminal of the cell module for treating exhaust gas. The heating unit heats the membrane-electrode assembly to a working temperature to perform an electrochemical reaction of fuel in the membrane-electrode assembly and generate electric power, and where nitrogen oxides in the exhaust gas electrochemically react to form nitrogen in the membrane-electrode assembly, and where carbon monoxide, hydrocarbons and particulate matter in the exhaust gas are catalyzed to form carbon dioxide and water by the oxidation catalyst, where the exhaust gas is decontaminated.
