Patent number: 10088243Abstract: This invention provides a thermal energy battery having an insulated tank containing a multitude of densely packed plastic tubes filled with a phase-change material (PCM, such as ice) that changes from solid to liquid and vice-versa. Energy is stored when the PCM transitions from liquid to solid form, and released when the PCM transitions back from solid to liquid form. The tubes are arranged vertically, span the height of a well-insulated tank, and are immersed in heat transfer fluid (HTF) contained within the tank. The HTF is an aqueous solution with a freezing point temperature below the freezing point temperature of the chosen PCM. The HTF remains in liquid form at all times during the operation of the battery. Diffusers located allow the HTF to be extracted uniformly from the tank, pumped and cooled by a liquid chiller situated outside the tank and then and inserted back into the tank.Type: GrantFiled: January 30, 2017Date of Patent: October 2, 2018Assignee: Promethean Power Systems, Inc.Inventors: Sorin Grama, Matthew H. Dorson, Rebecca Christianson

Patent number: 7066973Abstract: A hydrocarbon fuel reformer for producing diatomic hydrogen gas is disclosed. The reformer includes a first reaction vessel, a shift reactor vessel annularly disposed about the first reaction vessel, including a first shift reactor zone, and a first helical tube disposed within the first shift reactor zone having an inlet end communicating with a water supply source. The water supply source is preferably adapted to supply liquid-phase water to the first helical tube at flow conditions sufficient to ensure discharge of liquid-phase and steam-phase water from an outlet end of the first helical tube. The reformer may further include a first catalyst bed disposed in the first shift reactor zone, having a low-temperature shift catalyst in contact with the first helical tube.Type: GrantFiled: May 2, 2000Date of Patent: June 27, 2006Assignee: Nuvera Fuel CellsInventors: Jeffrey M. Bentley, Lawrence G. Clawson, William L. Mitchell, Matthew H. Dorson

Patent number: 6986797Abstract: An auxiliary reactor for use with a reformer reactor having at least one reaction zone, and including a burner for burning fuel and creating a heated auxiliary reactor gas stream, and heat exchanger for transferring heat from auxiliary reactor gas stream and heat transfer medium, preferably two-phase water, to reformer reaction zone. Auxiliary reactor may include first cylindrical wall defining a chamber for burning fuel and creating a heated auxiliary reactor gas stream, the chamber having an inlet end, an outlet end, a second cylindrical wall surrounding first wall and a second annular chamber there between. The reactor being configured so heated auxiliary reactor gas flows out the outlet end and into and through second annular chamber and conduit which is disposed in second annular chamber, the conduit adapted to carry heat transfer medium and being connectable to reformer reaction zone for additional heat exchange.Type: GrantFiled: May 2, 2000Date of Patent: January 17, 2006Assignee: Nuvera Fuel Cells Inc.Inventors: Lawrence G.

Patent number: 6861169Abstract: Interconnection layouts are described that are particularly effective in the construction of a steam reformer/fuel cell combination for providing domestic heat and/or hot water as well as electricity. A distinguishing feature of the interconnections is that they permit the operator to optimize the efficiency of operation of the integrated system, and provide a higher efficiency at optimum operation compared to prior art designs. Combinations of reformer/fuel cell systems with conventional furnaces or boilers are also described.Type: GrantFiled: May 8, 2002Date of Patent: March 1, 2005Assignee: Nuvera Fuel Cells, Inc.Inventors: Mark R.
