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.

Abstract: A safety control system for a fuel-consuming apparatus includes a switching assembly. The switching assembly includes a first end electrically connected to a power source node, a second end electrically connected to an input power node of a fuel safety shutoff valve of the fuel-consuming apparatus, and one or more switch units serially connected between the first and second ends. Each of the switch units is configured to be switched on or off based on a corresponding one of one or more environmental conditions of the fuel-consuming apparatus. An electrical connection path between the first and second ends is deactivated upon at least one of the one or more switch units being switched off to stop supplying of fuel into the fuel-consuming apparatus.

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: Closed loop filtration systems and methods of the present teachings can provide liquid reformable fuels enriched in light end hydrocarbons and/or having reduced content of sulfur and/or other impurities. Such enriched liquid reformable fuels can be used in fuel cell systems having a vaporizer and hydrocarbon fuel reformer such that the fuel cell system can experience less deleterious impact on its components, for example, coking. Filter elements for use in the systems and methods also are provided.
