“…22–24 The fluorite-spinel composite Ce 0.8 Gd 0.2 O 2− δ –FeCo 2 O 4 (CGO20–FCO) is a suitable example of such a material, providing a stable structure and sufficient oxygen permeability. 25–27 The presence of both phases is key to ensure good percolation, which leads to a stable oxygen flux, and sufficient performance of the composite. 14,15 This means that the concentrations of the individual phases should be above the percolating threshold, which is generally reported as 30 vol%.…”

Mixed ionic-electronic conducting (MIEC) membrane reactors are a promising technology for H 2 production through coupling of H 2 O splitting with CO 2 capture. To meet the high reliability requirement to the membrane reactors for an industrial process, it is necessary to develop membrane materials with high mechanical strength and high chemical stability. In this w o r k , a s e r i e s o f x w t % Y S Z -( 9 8 − x ) w t % La 0.7 Sr 0.27 Cr 0.4 Fe 0.6 O 3−δ -2 wt % CuO (x = 40, 50, 60 and 70; denoted as YL4, YL5, YL6, and YL7, respectively) dual-phase membranes were prepared for coupling water splitting with CO 2 capture. The results demonstrate that the mechanical strength of the dual-phase membrane increases significantly with the addition of YSZ and is much higher than that of the single perovskite material LSCF. The conductivity and H 2 production rates increase in the order of YL4 > YL5 > YL6 > YL7. The structure stability of the perovskite phase in dual-phase membranes increases with the content of YSZ phase under the operation condition of membrane reactors. The YL6-based membrane reactor was operated steadily for 290 h, indicating that it is a promising membrane material for H 2 production by coupling water splitting with CO 2 capture.
