    Abstract: A flow field plate for fuel cell applications includes a metal with a carbon layer disposed over at least a portion of the metal plate. The carbon layer is overcoated with a silicon oxide layer to form a silicon oxide/carbon bilayer. The silicon oxide/carbon bilayer may be activated to increase hydrophilicity. The flow field plate is included in a fuel cell with a minimal increase in contact resistance. Methods for forming the flow field plates are also provided.

    Abstract: A linerless engine includes a casting defining a bore having an inner surface and a central longitudinal axis. The casting is formed from a castable aluminum-silicon alloy including silicon particles present a range of from about 11 to about 12.5 parts by weight. The inner surface has a surface variation defined by at least some of the silicon particles protruding toward the axis for from about 0.6 to about 1.5 microns. The linerless engine includes a piston slideably disposed within the bore and configured for translating along the axis, wherein the piston is formed from an aluminum alloy and includes a body having a skirt portion coated with a first coating, and at least one ring encircling and in contact with the body. The ring is coated with a diamond-like coating that is free from degradation when in contact with the at least some of the silicon particles.

    Abstract: Hydrogen gas flow from high pressure storage to a lower pressure hydrogen-using device is managed using one or more axial flow pressure regulators comprising a cup-shaped housing with an inlet for high pressure hydrogen gas at one end of the flow axis and a closure with a low pressure hydrogen outlet at the other end of the flow axis. A piston head with a piston stem are aligned on the flow axis and a hydrogen flow passage is formed up the stem and through the piston head to the hydrogen flow outlet. One or more combinations of a corrugated tubular bellows (or like expansive sealing vessel) with static seals attaching one bellows end to the piston stem or head and the other bellows end to the housing or closure are used to accommodate axial movement of the piston while isolating and containing hydrogen gas flow from a high pressure chamber at a flow entrance to the piston stem to a low hydrogen pressure chamber at the piston head and closure outlet.
