Highly performing perovskite-based anodes for methane mixtures-fueled solid oxide fuel cells (SOFC) are proposed. Catalytic activities of La_0.6Sr_0.4Fe_1-xPd_xO_3-δ (LSFPd) with x = 0.05, 0.1 toward dry reforming of methane (DMR) and partial oxidation of methane (POM) reactions are investigated. The addition of (30 wt%) Ce_0.85Gd_0.15O_2-δ (GDC) and of (30 wt%) Ni(5 wt%)-GDC to the perovskite compounds was evaluated to enhance both electrocatalytic and electrochemical properties. Electrolyte-supported cells based on La_0.8Sr_0.2Ga_0.8Mg_0.2O_3-δ (LSGM) pellets and LSFPd perovskite oxides at both electrodes are fabricated and tested using CH₄, CH₄/Ar and CH₄/CO₂ mixtures in the 750–850 °C temperature range. Fuel cell tests using anodic mixtures such as LSFPd/GDC and LSFPd/Ni-GDC are also performed. A discussion based on the comparison between catalytic and electrochemical results and on the possible reforming and/or oxidation reactions taking place at the anode is detailed.
