Abstract: A high temperature electrochemical cell includes a solid electrolyte separating a cathode and an anode, an anode flow field adjacent the anode, a cathode flow field, having an exhaust gas stream pathway, downstream from the cathode, and a thermal management system including a controller programmed to, in response to the exhaust gas stream temperature input, activate at least one component, configured to reduce temperature of the exhaust gas stream to a temperature within a threshold range corresponding to a temperature range promoting condensation of Cr-containing gas into solid, liquid, or aqueous Cr2O3 and H2CrO4, the high temperature electrochemical cell having an operating temperature of about 600-1000° C.

Abstract: A high temperature electrochemical cell component includes a bulk portion and a surface portion including one or more alkaline earth metal-containing, cobalt free and nickel free, oxides reactive with Cr(HO2)2 such that a most stable reaction between each one of the oxides and the Cr(HO2)2 has a reaction energy of about ?0.1 to ?0.35 eV/at, the oxide(s) being non-reactive with water, the high temperature electrochemical cell having an operating temperature of about 600-1000ºC.

Abstract: A high efficiency operator assembly is for a valve for controlling flow through a passage, the valve including a closure element movable between a closed position at which the member substantially obstructs the passage and an open position. The operator assembly includes a movable stem having opposing ends, a first end being connectable with the closure element such that displacement of the stem moves the closure element between the open and closed positions. A stem driver is rotatable about a central axis, engaged with the stem, and configured to displace the stem when the driver angularly displaces about the axis and an input device is rotatable about the axis. A lock mechanism or a clutch is engageable with the stem, the stem driver, or the input device to retain the closure element at a particular position when the input device remains at a particular angular position about the input axis.

Abstract: A mobile hydrogen delivery system for delivering a compressed stream of hydrogen at pressures up to 15000 psig. The mobile hydrogen delivery system includes a hydrogen compression system, a gaseous hydrogen storage system, and a delivery system for supplying hydrogen to end users. A mobile platform supports the hydrogen compression system, the gaseous hydrogen storage system, and the dispensing system. The mobile platform may be any platform, such as a trailer, capable of being pulled, pushed, or supported by any type of vehicle, such a truck, train, boat, tractor, etc.

Abstract: A hydrogen storage and delivery system utilizing a hydrogen storage material to store hydrogen in hydride form. The hydrogen storage and delivery system utilizes a venting mechanism including a thermal fuse designed to melt away at a given temperature thereby venting the stored hydrogen to the atmosphere.
