Systems and methods are provided for hydrogen generation utilizing two or more liquid fuel components, using a fuel delivery system comprising a single reversible or bi-directional pump co-operable with flow control means comprising passive or active valves to deliver two or more fuel components to a mixing zone, reaction zone, or reaction chamber of a hydrogen generation system. The pump is operable in a forward direction to deliver one fuel component, and in a reverse direction to deliver a second fuel component. Control of the pump speed, direction and duty cycle of the pump in continuous or pulsed modes provides for delivery of first and second fuel components in desired proportions, to control hydrogen generation. The system also allows for dilution, mixing and flush cycles to be provided using a single pump, reducing the number of active elements required for fuel delivery and flow control in systems using two or more liquid fuel components.

Systems and methods for generating hydrogen gas

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.

Hydrogen generating fuel cartridge with volume exchange configuration

An arrangement for generating hydrogen gas utilizes differential pressure to transport fuel and spent fuel components without requiring an electrically powered fuel delivery pump.
