Catalytic converter to treat combustion exhaust gases

摘要

#CMT# #/CMT# The catalyst (10), for cleaning a motor exhaust gas, has en electrode (16) in physical contact with a layer (12) of a catalytic active material to convert gas components. An electrical pump voltage is applied to the electrode. A solid electrolyte layer (14) is in physical contact with the electrode and/or a further electrode (18) as an open-pore anode, forming an electro-chemical cell with the electrodes. #CMT#USE : #/CMT# The catalyst is for cleaning a motor exhaust gas. #CMT#ADVANTAGE : #/CMT# The catalyst effectively removes nitrogen oxide from the exhaust gas. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic section through the catalyst. 10 : catalyst 12 : catalytic layer 14 : solid electrolyte 16,18 : electrodes #CMT#METALLURGY : #/CMT# The solid electrolyte contains zirconium dioxide.
