摘要: Abstract A novel cell structure for low-temperature SOFC was proposed, using porous stainless steel support substrates combined with thin hydrogen permeable Pd layers, thin-film proton conductor, and cathode. Metallic supports consist of sintered ferritic spherical powders whose thermal expansion coefficient is close to that the layers conductive electrolytes. To prepare cell, both 1.2-μm thick Sr(Zr0.8Y0.2)O3−δ electrolyte layer 100-nm (La0.6Sr0.4)(Co0.2Fe0.8)O3−δ cathode were deposited by pulsed laser deposition (PLD) on a Pd-coated substrate. The power generation performance at low temperature 400 °C demonstrated in this proposed first time, while obtained density still improvements are required.
