Abstract: Embodiments of the present invention relate to a fluid distribution system. The system may include one or more electrochemical cell layers, a bulk distribution manifold having an inlet, a cell layer feeding manifold in direct fluidic contact with the electrochemical cell layer and a separation layer that separates the bulk distribution manifold from the cell feeding manifold, providing at least two independent paths for fluid to flow from the bulk distribution manifold to the cell feeding manifold.

Abstract: Embodiments of the present invention relate to a flexible fluid enclosure interface system comprising a flexible fluid enclosure, one or more components and one or more strain absorbing interfaces in contact with the flexible fluid enclosure and the one or more components.

Abstract: Embodiments of the present invention relate to a portable fuel cell power source including an expandable enclosure, a first reactant contained within the enclosure, one or more fuel cells and a fluid port positioned in the expandable enclosure and adapted to be in fluidic communication with the one or more fuel cells. The enclosure may also include an opening to insert a second reactant. When the first reactant is contacted with the second reactant a fuel is generated for use with one or more of the fuel cells. The volume of the portable fuel cell power source in a collapsed state may be smaller than the volume of the amount of first reactant and second reactant needed to substantially consume the first reactant in a fuel generation reaction.

Abstract: Embodiments of the invention relate a charge indicator for determining the mass of a fluid contained within a fluid enclosure, wherein the charge indicator responds to a deformation of a solid component in contact with the fluid and wherein the deformation is a function of the mass of fluid contained within the fluid enclosure.

Abstract: A fuel cell module power delivery control system monitors the status of a fuel cell module to control power delivery of the fuel cell module, such as to prevent the fuel cell module from reaching an overload condition.

Abstract: Corrugated flow field plates for use in fuel cells typically comprise a plurality of parallel open-faced fluid flow channels for the fuel cell reactants. Complex flow paths, such as serpentine flow paths, may be created in such corrugated flow field plates by incorporating channel couplings within the plate or by attaching coupling subassemblies to the plate. The plates are particularly suitable for use in solid polymer electrolyte fuel cells.
