A solid oxide fuel cell includes an anode layer, an electrolyte layer over a surface of the anode layer, and a cathode layer over a surface of the electrolyte layer. The cathode layer includes a cathode bulk layer, a porous cathode functional layer at an electrolyte, an intermediate cathode layer partitioning the cathode bulk layer and the porous cathode functional layer, the porous intermediate cathode layer having a porosity greater than that of the cathode bulk layer. The solid oxide fuel cells can be combined to form subassemblies that are bonded together to form solid oxide fuel cell assemblies.

SOFC cathode and method for cofired cells and stacks

A solid oxide fuel cell includes a tube, a spacer element, a catalytic substrate and an anode current collector. The solid oxide fuel cell further includes a spacer element disposed within the tube. The solid oxide fuel cell further includes a catalytic substrate disposed within the anode current collector electrically contacting the anode of the tube and providing an electrical current path inside the tube past the catalytic substrate to the inlet opening.

Current collector for solid oxide fuel cell tube with internal fuel processing

A solid oxide fuel cell comprises a plurality of tubes, each having an anode, electrolyte and cathode. Anode and cathode current collectors are mounted on the tubes. The anode current collector electrically connects to the anode and can have a contact with the anode. The cathode current collector electrically connects to the cathode and can have a contact with the cathode. An electrically conductive sealant may be positioned between the anode of one tube and the cathode current collector of another tube.

Solid oxide fuel cell with improved current collection

A gas delivery substrate and method of manufacture is disclosed. A thermoplastic extrusion compound is created comprising a ceramic material and a thermoplastic resin, a green body is formed by thermoplastic extrusion of the compound, and the green body is sintered to form the gas delivery substrate. Such gas delivery substrates may be thin walled, highly porous and have secondary operations such as crimping and machining done prior to sintering.
