Abstract: A solid oxide fuel cell comprises a tube forming an anode, electrolyte and cathode, and a catalytic substrate is positioned within the tube. Such solid oxide fuel cells are highly compact and lightweight, and can be used in portable applications.

Abstract: 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.

Abstract: 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.

Abstract: A modular battery terminal connector assembly designed to connect batteries together in series or in parallel. The connector assembly has a first electrically conductive elbow member, an electrically conductive connecting member and a second electrically conductive connecting member. The first conductive elbow member is coupled at one end to a first terminal of a first battery, preferably, by a toolless socket which frictionally engages and grips the first terminal of the first battery. The other end of the first conductive elbow member is coupled to a second terminal of a second battery, preferably, by a toolless socket. The conductive connecting member interconnects the first and second conductive elbow members together, preferably, by a pair of toolless sockets. In some embodiments, the toolless sockets are fixedly coupled to the elbow members, while the connecting member is either a single rod or a plurality of rods interconnected by sleeve members.
