<p>The MIEC La<sub>1.5</sub>Sr<sub>0.5</sub>Ni<sub>1-y</sub>Fe<sub>y</sub>O<sub>4</sub> (<em>y</em>=0.1-0.4) oxides have been studied as cathode materials with La<sub>0.88</sub>Sr<sub>0.12</sub>Ga<sub>0.82</sub>Mg<sub>0.18</sub>O<sub>3-δ</sub> (LSGM) electrolyte. Total conductivity, thermal expansion, oxygen nonstoichiometry, and chemical compatibility with LSGM and Ce<sub>0.8</sub>Sm<sub>0.2</sub>O<sub>1.9</sub> (SDC) were determined. The following fuel cells were tested: La<sub>1.5</sub>Sr<sub>0.5</sub>Ni<sub>1-y</sub>Fe<sub>y</sub>O<sub>4</sub> (<em>y</em>=0.1, 0.2, 0.3, 0.4)/SDC/LSGM/Sr<sub>2</sub>N<sub>0.75</sub>Mg<sub>0.25</sub>MoO<sub>6</sub> (SNMM) and La<sub>1.5</sub>Sr<sub>0.5</sub>Ni<sub>0.6</sub>Fe<sub>0.4</sub>O<sub>4</sub>/SDC/LSGM/SDC/NiO-SDC. For the former, the maximum power densities were 218, 274, 222, and 390 mW/cm<sup>2</sup> at 850 °C in case of <em>y</em> equal to 0.1, 0.2, 0.3, and 0.4, respectively. The latter cell showed maximum power density of 341 mW/cm<sup>2</sup> at 850°C.</p>
