Chromite anodes in LWO PC‐SOFC: Chemically compatible LSCN/LWO symmetric cells show the high protonic conductivity and p‐type electronic conductivity of LSCN in reducing atmospheres. This allows to avoid blending with other protonic or electronic materials and enlarges the surface area. An R p of 2.68 Ω cm 2 at 750 °C and performance in LF‐limited processes demonstrate the potential of LSCN as anode material.
