Embodiments of the present disclosure relate to a hot press and methods of using the hot press. In an embodiment, the hot press can include a pressing element including a flared body. In another embodiment, the hot press can include a compression surface. The compression surface can include a first layer including a monocrystalline material and a second layer including a polycrystalline material, wherein the monocrystalline material and the polycrystalline material include a same primary compound. In a further embodiment, a sample including more than one layer of ceramic oxide material can be hot pressed without a die.

Hot press and method of using

The present disclosure is directed to an integrated SOFC stack including, a first cell having a cathode layer, an electrolyte layer overlying the cathode layer, and an anode layer overlying the electrolyte layer. The SOFC stack also includes a second cell having a cathode layer, an electrolyte layer overlying the cathode layer, and an anode overlying the electrolyte layer. The SOFC stack further includes a ceramic interconnect layer between the first cell and the second cell, the ceramic interconnect layer having a first high temperature bonding region along the interfacial region between the first cell and the ceramic interconnect layer. The ceramic interconnect layer also includes a second high temperature bonding region along the interfacial region between the second cell and the ceramic interconnect layer.

SOFC stack having a high temperature bonded ceramic interconnect and method for making same

An anisotropic coefficient of thermal expansion (CTE) cathode of a solid oxide fuel cell (SOFC) is formed by placing a layer of perovskite powder between two platens, and sintering the layer while applying pressure to the platens, thereby forming the anisotropic CTE cathode. The perovskite can be lanthanum strontium manganite (LSM).

An anode component of a solid oxide fuel cell is formed by combining a relatively coarse yttria-stabilized-zirconium (YSZ) powder, that is substantially composed of elongated particles, with a relatively fine NiO/YSZ or NiO powder of reduced particle size, whereby, upon sintering the combined powders, the coarse YSZ powder forms a microstructural cage of open porosity wherein the fine powder is distributed through the open porosity of the cage. A method of forming a cathode component includes combining a coarse YSZ powder, that is substantially composed of elongated particles, with a fine lanthanum strontium manganite powder of reduced particle size, whereby, upon sintering the combined powders, the coarse YSZ powder forms a microstructural cage of open porosity, wherein the fine powder is distributed through the open porosity of the cage.

Reduction-oxidation-tolerant electrodes for solid oxide fuel cells

The disclosure is directed to a solid oxide fuel cell stack. The solid oxide fuel cell stack includes at least two solid oxide fuel cells. The two solid oxide fuel cells share a common electrode.
