A hydrogen generator () is provided which comprises a third chamber () containing a catalyst (), a first chamber () containing a fluid, a second chamber () containing a material that reacts with the fluid in the presence of the catalyst to generate hydrogen gas, and a valve () movable from a first position in which the flow of fluid along a pathway including the first, second and third chambers is enabled, to a second position in which the flow of fluid along the pathway is prevented.

Microcartridge hydrogen generator

A bipolar plate comprising a fluid barrier and a sealing frame formed around and overlaping the perimeter of the fluid barrier. The fluid barrier is placed in a mold and then a polymer is injected into the mold, thereby forming the sealing frame around the fluid barrier such that the sealing frame overlaps the perimeter of the fluid barrier. Because there are no surfaces to seal between the perimeter of the fluid barrier and the sealing frame, gaskets or other sealing surfaces are not required. A bipolar plate is further provided comprising a fluid barrier having the perimeter of the fluid barrier between a preformed cathode sealing frame and an anode sealing frame. The anode and cathode sealing frames are adapted to receive an overlapped portion of the perimeter of the fluid barrier. The anode and cathode sealing frames are then bonded together to form a fluid tight seal.

Very thin, light bipolar plates

A device for generating hydrogen gas is provided. The device () comprises a first hydrogen-containing composition () that reacts with a second composition to evolve hydrogen gas; a dispenser () adapted to apply the first composition to a first porous member (); and a conduit () adapted to supply the second composition to the first porous member. In a preferred embodiment, the first composition is selected from the group consisting of hydrides, borohydrides and boranes, the second composition is water, and the dispenser is spring-loaded and is charged with the first composition. As the first composition reacts with water at the interface to evolve hydrogen gas, the dispenser forces the reaction product across the interface and out of the dispenser, where it will not interfere with the progress of the hydrogen evolution reaction.

Solid chemical hydride dispenser for generating hydrogen gas

An apparatus and method apply water to a hydrogen-containing composition, such as a hydride, in the presence of a catalyst that promotes hydrolysis to generate hydrogen in a controlled manner. The amount of catalyst used can be carefully tailored so that the reaction rate is limited by the amount of catalyst present (passive control) or it can be sufficiently large so that the reaction is controlled by the rate of water addition (active control).
