(a) I–V curve and the corresponding power densities of the L-PBMTO (T=Mn, Co, Ni and Fe) electrode using humidified (3% H2O) H2 and ambient air as the oxidant at 800 °C. (b) I–V curve and the corresponding power densities of the PrBaMn1.7Co0.3O5+δ (L-PBMCO) and PrBaMn1.7Ni0.3O5+δ (L-PBMNO) electrode using C3H8 as fuel and ambient air as the oxidant at 800 °C. (c) Electrochemical performances of L-PBMNO anode in C3H8 at 700 °C under a constant voltage of 0.6 V. (d) Comparison of the maximum power density at 800 °C in H2 of the present work and other studies in the literature28,29,30,31,32,33,34.
