We report on an excellent anode‐supported H+‐SOFC material system using a triple conducting (H+/O2−/e−) oxide (TCO) as a cathode material for H+‐SOFCs. Generally, mixed ionic (O2−) and electronic conductors (MIECs) have been selected as the cathode material of H+‐SOFCs. In an H+‐SOFC system, however, MIEC cathodes limit the electrochemically active sites to the interface between the proton conducting electrolyte and the cathode. New approaches to the tailoring of cathode materials for H+‐SOFCs should therefore be considered. TCOs can effectively extend the electrochemically active sites from the interface between the cathode and the electrolyte to the entire surface of the cathode. The electrochemical performance of NBSCF/BZCYYb/BZCYYb‐NiO shows excellent long term stability for 500 h at 1023 K with high power density of 1.61 W cm−2. Triple play: Proton‐conducting solid oxide fuel cells (H+‐SOFCs) have received a great deal of attention for intermediate‐temperature SOFCs. However, the performance of the H+‐SOFCs is limited by the cathode material. Triple‐conducting oxide cathodes could enhance the electrochemical performance by extending the electrochemically active site to the entire surface of cathode.
