A controller for a fuel cell based power generator includes a memory and a processor configured to execute executable instructions stored in the memory to receive a pressure in an anode loop of the fuel cell based power generator, wherein the anode loop includes a hydrogen generator and an anode loop blower, and control the anode loop blower such that the hydrogen generator provides hydrogen to an anode of a fuel cell via the blower and the anode loop at a controlled pressure. In further embodiments, the temperatures of the fuel cell and hydrogen generator are independently controlled.

Fuel cell based power generator with pressure controlled anode loop

A fuel cartridge includes an inlet manifold and a plurality of fuel beds containing a hydride material. A first end of each of the fuel beds is coupled to the inlet manifold to receive wet hydrogen via the inlet manifold. An outlet manifold is coupled to a second end of each of the fuel beds to receive dry hydrogen from the fuel beds. The fuel beds are laterally spaced from each other providing space for flow of coolant fluid therebetween. Valves may be included in the inlet and outlet manifolds.
