摘要: Abstract Co-existence of intra-anode and conventional triple phase boundary (TPB) is reported for the first time in core (YSZ)–shell (Ni) electroless anode cermet. A mathematical model proposed determination TPB length has been validated experimentally. Retention longer even after repeated redox cycling responsible relatively lower conductivity degradation such cermets. Existence results significant improvement electrochemical performance. Single cells with exhibit a current density 2.5 A cm −2 compared to (1.7A cm ) at 800 °C, 0.7 V.
