Abstract

Multi-layered ceramics for electrochemical flue gas purification were fabricated by tape casting and lamination or by multi-layer tape casting. The sintered bodies were studied by scanning electron microscopy and electrochemical impedance spectroscopy. It was shown that the samples made by multi-layer tape casting had a lower resistance than the laminated samples. This was mainly due to
a decrease of the resistance of the middle frequency arc, attributed to charge transfer close to the triple phase boundary. The cells showed ability to oxidize propene both under open circuit voltage and when polarized.
