Abstract: Provided are therapeutic compositions containing microbial populations for prevention, treatment and reduction of symptoms associated with a dysbiosis of a mammalian subject such as a human.

Abstract: A hydrogen generation fuel cartridge system which can be removably connected to a fuel cell power module is disclosed. The removable hydrogen generation fuel cartridge comprises a fuel storage module and a hydrogen generation system balance of plant (BOP) that is interchangeable with each module. All controls are preferably contained in the BOP. A heat exchanger may be employed to control the temperature of the cartridge and components such as the reaction chamber.

Abstract: A packaging system and method are disclosed for delivering a solid fuel component in pre-measured quantities for hydrogen generation. Each quantity may be contained in a sealed pack or in a plurality of packs connected in series for indexing through a solid fuel dispenser. The solid fuel may be a boron hydride that is stored in its dry form and mixed with a liquid, as needed. The liquid may include water. The solid fuel component may be provided in various forms, including granules, pellets and powder.

Abstract: A fuel cell power system including a removable hydrogen generation fuel cartridge module and method are disclosed. The fuel cell power system incorporates one or more of the following elements: a) a mechanism for fuel regulation which may be controlled by an auxiliary module; b) a means for heat exchange in communication with the reactor and/or the fuel cartridge body; c) an air filter for the incoming oxidant gas feed to the power module; d) a means to transfer mechanical energy from the power module to the fuel cartridge; and e) a means for heat exchange.

Abstract: Systems and methods are disclosed for monitoring at least two system parameters (such as system temperature or pressure, or system pressure at two different locations) of a hydrogen generation system and controlling hydrogen generation from a fuel solution. The system comprises a hydrogen generator having a fuel chamber for a liquid fuel, a reactor chamber where the fuel undergoes a reaction to produce hydrogen, and at least two sensors in communication with the reactor chamber, the sensors measuring at least two system parameters of the hydrogen generator. The methods include control sequences for controlling the fuel flow rate to the reactor based on the sensed parameters.

Abstract: Solid self-stabilized borohydride fuel compositions, fuel cartridges, related methods of preparation and hydrogen generation are provided. The fuel compositions comprise mixtures of at least one borohydride salt with a cation selected from the group consisting of alkali metal cations, alkaline earth metal cations, aluminum cation, zinc cation, and ammonium cation, preferably sodium borohydride, and at least one hydroxide salt with a cation selected from the group consisting of alkali metal cations, alkaline earth metal cations, aluminum cation, zinc cation, and ammonium cation, preferably sodium hydroxide.
