Abstract: Provided herein generally are methods of accounting for hydrogen (H2) in a natural gas (NG) stream, i.e., a NG/H2 blend, from a public NG utility to residential and/or business facility fuel cell (FC) systems, where the NG/H2 blend powers the FC systems and the volume of NG/H2 blend supplied to each FC systems is measured. Such measurements along with other data of the operation of the FC system, such as the volume of NG/H2 blend or an increased volume of NG, can be reported or transmitted to the public NG utility for each residential and/or business facility FC system supplied with the NG/H2 blend, where a reduced carbon footprint can be determined for the use of the NG/H2 blend by the FC system(s).

Abstract: The present teachings provide multi-reformable fuel delivery systems and methods that can deliver, without the use of a liquid pump, any hydrocarbon fuel, i.e., a liquid or gaseous reformable fuel, for example, to at least one of a reformer, a vaporizer, a fuel cell stack, an afterburner and other assemblies and components of a fuel cell unit or system, More specifically, gas pressure can be used to control and deliver gaseous reformable fuels and/or liquid reformable fuels in the delivery systems and methods of the present teachings. The delivery systems and methods also can apply to the delivery of a liquid reactant such as water and gaseous reactants such as an oxygen-containing gas (e.g., air) and steam.

Abstract: A liquid fuel reformer includes a fuel vaporizer which utilizes heat from an upstream source of heat, specifically, an electric heater, operable in the start-up mode of the reformer, and therefore independent of the reforming reaction zone of the reformer, to vaporize fuel in a downstream vaporization zone.

Abstract: A liquid fuel reformer (400) includes a fuel vaporizer (415) which utilizes heat from an upstream source of heat, specifically, an electric heater (406), operable in the start-up mode of the reformer (400), and therefore independent of the reforming reaction zone of the reformer, to vaporize fuel in a downstream vaporization zone.

Abstract: Integrated liquid fuel catalytic partial oxidation (CPOX) reformer and fuel cell systems can include a plurality or an array of spaced-apart CPOX reactor units, each reactor unit including an elongate tube having a gas-permeable wall with internal and external surfaces, the wall enclosing an open gaseous flow passageway with at least a portion of the wall having CPOX catalyst disposed therein and/or comprising its structure. The catalyst-containing wall structure and open gaseous flow passageway enclosed thereby define a gaseous phase CPOX reaction zone, the catalyst-containing wall section being gas-permeable to allow gaseous CPOX reaction mixture to diffuse therein and hydrogen rich product reformate to diffuse therefrom. The liquid fuel CPOX reformer also can include a vaporizer, one or more igniters, and a source of liquid reformable fuel. The hydrogen-rich reformate can be converted to electricity within a fuel cell unit integrated with the liquid fuel CPOX reactor unit.
