Structural and Electrochemical Properties of Lanthanum Silicate Apatites La₁₀Si_6−x−0.2Al_xZn_0.2O_27−δ for Solid Oxide Fuel Cells (SOFCs)

Figure 1

Schematic illustration of the all porous single-chamber SOFC. Methane (CH₄) is nourished at the anode side, while air (O₂) is introduced at the cathode and conveyed by the permeable electrolyte to the catalytic anode.
