PROBLEM TO BE SOLVED: To provide an electro-catalytic honeycomb for exhaust emission control.SOLUTION: The electro-catalytic honeycomb for exhaust emission control is used for controlling oxygen-rich combustion emission, and includes a honeycomb structure, solid oxide layer and cathode layer. The honeycomb structure includes an anode, a plurality of gas channels and a shell. The anode forms a backbone of the honeycomb structure. The gas channel is formed in the backbone and causes the oxygen-rich combustion emission to pass. The shell covers one outer surface of the anode. The solid oxide layer adheres to one inner surface of the anode and is connected to the shell to encapsulate the anode. The shell has a tube wall facing the gas channel. The cathode layer adheres to the tube wall, the anode has reduction atmosphere and the cathode layer has oxidation atmosphere. With this arrangement, the reduction atmosphere and the oxidation atmosphere generate electromotive force between the anode layer and the cathode layer, nitrogen oxide in the oxygen-rich combustion emission is decomposed with the anode layer. |
