A novel design of an electrochemical reactor for filtering and continuouscombustion of soot particles was developed. Such a reactor consists of a porous, oxygen-ion conducting material covered by catalytically active, electron-conductive electrodes, electrical connections and an external power supply. The manufacturing process was developed for high-porosity, ion- and electron-conducting ceramic monoliths from nanosize powders by extrusion followed by coating techniques. The performed catalytic tests proved that the efficiency of the reactor for soot removal is above 90% at low flow conditions (GHSV = 13 000-1) and 75% for high flow (GHSV = 39 000-1) in the temperature range 250-500°C.
