Abstract

In this study porous cell stacks for electrochemical flue gas purification were fabricated using tape casting and lamination followed by sintering. Two different mixtures of pore formers were used; either a mixture of two types of graphite or a mixture of graphite with polymethyl methacrylate micro-particles. It was shown that the porous cell stacks fabricated with polymethyl methacrylate had a higher porosity but a similar back pressure compared to the porous cell stacks fabricated with only graphite as a pore former. This was due to a high back pressure of the electrolyte layer. The porous cell stacks fabricated with polymethyl methacrylate as a pore former seem to be well suited for i.e. caption of soot particles. Furthermore, the back pressure of the electrode layer was significantly reduced when using polymethyl methacrylate pore formers. However, a better interconnectivity of the pores formed by the polymethyl methacrylate pore former, especially in the electrolyte layer, is needed, in order to lower the back pressure of the porous cell stack.
