                      highly interesting method, particularly for the
                      high-temperature range of600 °C − 900 °C, due to the low
                      efficiency losses that can be reached. It was shown thateven
                      for this high-temperature range the utilization of a
                      CO-shift catalyst leads to aconsiderable increase of the
                      CO-conversion, at least up to 900 °C compared to
                      anoperation mode without catalyst[1]. However, the harsh
                      conditions of an IGCC-powerplant lead to very challenging
                      operation conditions for the dense H2-selectivemembranes as
                      well as for the CO-shift-catalysts.The present work aimed at
                      the development of thermo-chemically and
                      microstructurallystable, active and compatible
                      membrane-catalyst systems for futurecatalytic CO-shift
                      membrane-reactors. Therefore, the ceramic mixed protonic
                      electronicconductors BaCe0.2Zr0.7Yb0.08Ni0.02O3−d and
                      La5.5WO12−d were combined with ironbased catalysts like
                      Fe/Cr/Cu-spinels. These materials were already studied
                      intensivelyregarding the planned applications and show very
                      good properties [2]. Additionally, formembrane-catalyst
                      systems it is strongly required that the combined components
                      donot influence each other negatively i.e. by diffusion or
                      reaction.Figure: SEM picture of a cross section through a

                      membrane reactor at 850 °C.The investigation identified
                      material combinations that seem to be highly applicablefor
                      future catalytic CO-shift membrane reactors in the
                      high-temperature range up to900 °C. As shown in the figure
                      above, the 86Fe14Cr-spinel catalyst and the
                      La5.5WO12−d-membrane show very good compatibility.
                      Additional investigations on membranereactorperformance,
                      long term stability and scale up are necessary.[1] D. van
