000860675 520__ $$aA novel, cost-efficient, all-ceramic Solid Oxide fuel Cell (SOFC) is investigated. The design includes a low-cost mechanical support material; a porous membrane made of a doped magnesium silicate, on the cathode (air) side of the cell. The manufacturing route involves a single step co-firing process at <1300°C of the support and all functional layers. This is significantly lower than the maximal temperature applied in the usual SOFC manufacturing sequence, but higher than the usual sintering temperature of the cathodes. So far, the effects of the use of magnesium silicate as support material and the co-firing production route on performance and lifetime of this SOFC concept are scarcely examined. Thus, the present investigations are analyzing the interactions between the support material and candidate cathode materials occurring during the high temperature sintering step. Various cathode materials are investigated. Inter-diffusion and secondary phase formations between the layers are characterized by means of energy dispersive X-ray spectroscopy and X-ray crystallography. The effect of chemical interactions on electrochemical performance is investigated with electrochemical impedance spectroscopy. As well, the outcomes of the co-firing on the macro scale geometry and the microstructural properties of selected cathode materials are evaluated.
