The hybrid systems of the present invention comprise a hydrogen gas generator, an electricity producing hydrogen consuming device, and an auxiliary power source wherein the auxiliary power source is capable of storing energy produced by hydrogen produced by the generator, and the electricity producing hydrogen consuming device and the auxiliary power source are connected in parallel to an energy consuming device.

Abstract: Hydrogen generators and power module systems that use solid chemical hydrides and acidic reagents for hydrogen storage and generation on demand are disclosed. The generators incorporate mechanisms for controlling the contact between solid chemical hydride and acidic reagents to control the rate of hydrogen generation and characteristics of the reaction products, including bulk density. The preferred systems of the present invention combine functions of fuel reagent storage, reaction chamber, and gas-liquid separation into a minimum number of components to reduce the balance of plant of hydrogen generation systems.

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.
