Systems and methods for controlling hydrogen generation
First Claim
1. A method for controlling hydrogen generation in a hydrogen generating system having a fuel chamber containing a fuel, and a reactor, comprising:
- detecting at least one system parameter; and
controlling the flow of the fuel from the fuel chamber to the reactor based on the detected at least one system parameter, wherein the at least one system parameter is system temperature, or at least two system parameters selected from the group consisting of a first pressure measured at a first location with respect to the reactor, a second pressure measured at a second location with respect to the reactor, and a |temperature within the system.|

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.
