Patent number: 9873101Abstract: An apparatus and method for enhancing the yield and purity of hydrogen when reforming hydrocarbons is disclosed in one embodiment of the invention as including receiving a hydrocarbon feedstock fuel (e.g., methane, vaporized methanol, natural gas, vaporized diesel, etc.) and steam at a reaction zone and reacting the hydrocarbon feedstock fuel and steam in the presence of a catalyst to produce hydrogen gas. The hydrogen gas is selectively removed from the reaction zone while the reaction is occurring by selectively diffusing the hydrogen gas through a porous ceramic membrane. The selective removal of hydrogen changes the equilibrium of the reaction and increases the amount of hydrogen that is extracted from the hydrocarbon feedstock fuel.Type: GrantFiled: January 27, 2015Date of Patent: January 23, 2018Assignee: CERAMATEC, INC.Inventors: Joseph J.

Patent number: 9819036Abstract: A reformer is disclosed in one embodiment of the invention as including a channel to convey a preheated plurality of reactants containing both a feedstock fuel and an oxidant. A plasma generator is provided to apply an electrical potential to the reactants sufficient to ionize one or more of the reactants. These ionized reactants are then conveyed to a reaction zone where they are chemically transformed into synthesis gas containing a mixture of hydrogen and carbon monoxide. A heat transfer mechanism is used to transfer heat from an external heat source to the reformer to provide the heat of reformation.Type: GrantFiled: November 23, 2015Date of Patent: November 14, 2017Assignee: CERAMATEC, INC.Inventors: Joseph J Hartvigsen, Singaravelu Elangovan, Piotr Czernichowski, Michele Hollist, Michael Boettcher

Publication number: 20170222245Abstract: A solid oxide fuel cell (SOFC) (100) for use in generating electricity while tolerating sulfur content in a fuel input stream. The solid oxide fuel cell (100) includes an electrolyte (106), a cathode (102), and a sulfur tolerant anode (104). The cathode (102) is disposed on a first side of the electrolyte (106). The sulfur tolerant anode (104) is disposed on a second side of the electrolyte (106) opposite the cathode (102). The sulfur tolerant anode (104) includes a composition of nickel, copper, and ceria to exhibit a substantially stable operating voltage at a constant current density in the presence of the sulfur content within the fuel input stream. The solid oxide fuel cell (100) is useful within a SOFC stack to generate electricity from reformate which includes synthesis gas (syngas) and sulfur content. The solid oxide fuel cell (100) is also useful within a SOFC stack to generate electricity from unreformed hydrocarbon fuel.Type: ApplicationFiled: April 21, 2017Publication date: August 3, 2017Inventors: Singaravelu Elangovan, Joseph J Hartvigsen
