摘要： An improved LSCF 6428 perovskite material of the type La12zSrx+zCo0.2+aFe0.8+bO3−δ wherein x=0.4, z=(0-0.1), a=(0.01-0.04), and b=(0.05-0.15) for use as an SOFC cathode having increased electronic and ionic conductivity. The general formula is similar to the prior art formulae (La0.6Sr0.4)1−zCo0.2Fe0.8O3−δ and La0.6Sr0.4Co0.2Fe0.8O3−δ but applies the z term to La and Sr independently as well as reducing the overall content of La. Further, by adding a small amount (a) of extra Co ions, catalytic activity, conductivity, and sinterability are further enhanced. Adding small amounts (b) of Fe and/or Fe and Co moderates the thermal expansion coefficient with no adverse effect on crystal structure or fuel cell performance. Improved sinterability, microstructure, and reduced film cracking result in high power density of fuel cells. An inherently low-cost solid state reaction method is described.

摘要： A cathode of a solid-oxide fuel cell includes a first ionic conducting layer, a second layer deposited over the first layer and formed from a mixed ionic and electronic conductor layer including an oxygen ion conducting phase, and a third layer deposited over the second layer and formed from a mixed ionic and electronic conductor layer. A sintering aid and pore formers are added to the second layer and the third layer to establish ionic, electronic, and gas diffusion paths that are contiguous. By adjusting the microstructure of the second and the third layer, a high performance low resistance cathode is formed that bonds well to the electrolyte, is highly electro-catalytic, and has a relatively low overall resistance. By using inexpensive and readily available substances as sintering aid and as pore formers, a low-cost cathode is provided.

摘要： A method for improving performance of an SOFC by impregnation of the cathode with metallic silver. A solution of AgNO3 in acetonitrile is imbibed into a perovskite cathode fabricated on a electrolyte layer supported by an anode, defining an SOFC cell. The cathode imbibition may be repeated a plurality of times as may be needed depending upon the thickness of the cathode. The amount of solution soaked into the cathode results a total final weight percent of Ag in the cathode between about 0.5% and about 10%. The cathode is then fired in air at high temperature to drive off the acetonitrile and to reduce the silver ions to metallic silver. In this way, cathode electrical resistance may be reduced by as much as 52%.

摘要： An SOFC structure having segmentation of the mixed layer on a cathode electrode to allow a higher fraction of ionic phase in a mixed layer, resulting in improved microstructure that provides higher specific surface area for electrochemical reaction. This is accomplished by using an MIEC layer over the segmented layer that supplies electrons laterally and vertically through the thickness of the mixed layer. Adequate connectivity between the cathode current collector and electrolyte for electrons is established, assuring efficient charge transfer and improved activity of the electrocatalyst in the porous cathode. Cell resistance is reduced and power output is improved. Further, the invention can efficiently incorporate a variety of functional layers on the anode electrode to improve protection from poisons and certain fuel mixtures that degrade cell performance, and can reduce stresses between fuel cell components while maintaining adequate connectivity with the anode current collector and electrolyte via an Ni-YSZ anode.
