An electrochemical-catalytic converter, which can remove nitrogen oxides (NO x ), carbon monoxide (CO), hydrocarbons (HCs) and particulate matter (PM) in exhaust gas and generate electric power simultaneously is described. The electrochemical-catalytic converter comprises a cell module (10), wherein nitrogen oxides are reacted electrochemically to form nitrogen, and wherein carbon monoxide, hydrocarbons and particulate matter are catalyzed to form carbon dioxide and water by an oxidation catalyst. |
