Номер: US20120231366A1
Автор: Eric D. Wachsman, Sean Robert Bishop
Принадлежит: University of Florida Research Foundation Inc

A fuel cell anode comprises a porous ceramic molten metal composite of a metal or metal alloy, for example, tin or a tin alloy, infused in a ceramic where the metal is liquid at the temperatures of an operational solid oxide fuel cell, exhibiting high oxygen ion mobility. The anode can be employed in a SOFC with a thin electrolyte that can be a ceramic of the same or similar composition to that infused with the liquid metal of the porous ceramic molten metal composite anode. The thicknesses of the electrolyte can be reduced to a minimum that allows greater efficiencies of the SOFC thereby constructed.

Автор: Lipilin Aleksandr S., Liplina Viktoria S
Принадлежит:

The invention relates to a modified planar cell with a solid-oxide solid electrolyte, a gas-diffuse anode, a cathode, a metal or oxide current path and a current-gas supply. The supporting solid electrolyte of the cell is in the form of a corrugated plate consisting of corrugations. In cross-section, the corrugations of the plate constitute an isosceles, identical-height trapezium, without a larger lower base with holes. The holes are formed on one side in the upper part of each corrugation, for supplying one of the reagents, e.g. fuel in case of a fuel cell. The corrugations are connected to one another at their base in order to form gas space channels of the cell. The gas space channels are in the form of inverted isosceles trapezia without a larger upper base and the angle α at their smaller base is 0.1 to 89.9°. The corrugated plate is connected to two opposing walls, a front wall and a rear wall. The latter is arranged perpendicular to the corrugations of the plate and thus of equal height, and is furnished with holes. The holes in one wall are used for introducing a second reagent, e.g. air in the case of a fuel cell, into each channel of the electrode environment in the form of inverted isosceles trapezia without the larger upper base and the holes of the other opposing wall for discharging the hypoxic mixture. On one side of the gas space channels constituting, in cross-section, an isosceles trapezium without larger lower base, the corrugated plate of the supporting solid electrode is coated with an electrode, e.g. a nickel-cermet anode in the case of a fuel cell. On the side of the gas space channels of the electrode environment, which are shaped in the form of inverted isosceles trapezia without the larger upper base, the plate is coated with a second, counter-electrode, e.g. a cathode based on strontium-lanthanum-manganite. The metallic box-like gas supply duct ensures the supply of reagents and the discharge of reaction products with a series of holes. ...

The present disclosure relates to garnet powder, a manufacturing method thereof, a solid electrolyte sheet using a hot press, and a manufacturing method thereof. In particular, the present disclosure provides a method for manufacturing Li 7 La 3 Zr 2 O 12 (LLZ) garnet powder including preparing a mixture by first dry mixing Li 2 CO 3 , La 2 O 3 , ZrO 2 , and Al 2 O 3 . The mixture is first calcinated for 5 to 7 hours in a temperature range of 800 to 1000° C. The calcinated mixture is ground to a powder with an average particle size of 1 to 4 μm through dry grinding. A cubic-phased LLZ garnet powder is prepared by second calcinating the ground mixture for 10 to 30 hours in a temperature range of 1100 to 1300° C.
