摘要： A fluid flow plate for an electrochemical fuel cell assembly comprises a first plurality of fluid flow channels extending across an area of the flow plate to define a flow field of the fluid flow plate. An array of first fluid transfer points is disposed along an edge of the flow field for communicating fluid into or out of the fluid flow channels. A gallery has a first peripheral edge portion bounded by the array of first fluid transfer points and at least two second peripheral edge portions each bounded by an array of second fluid transfer points disposed along fluid access edges of the fluid flow plate. The at least two second peripheral edge portions are disposed at oblique angles to the first peripheral edge portion such that the total length of the any of second fluid transfer points is at least as long as, and preferably longer than, the length of the array of first fluid transfer points. Disposing the at least two second peripheral edge portions at oblique angles to the first peripheral edge portion enables the lengths of the second peripheral edge portions of each gallery to be increased compared to the length of the first fluid transfer points (i.e. width of the active flow field area) which optimizes fluid distribution into the channels of the flow plate.

摘要： A thermal insulation device includes a first plate, a second plate formed to nest adjacent the first plate with a gap between the first and second plates, a porous material disposed between the plates, and a sealing layer disposed between the first and second plates such that the porous material is sealed from ambient at a pressure less than ambient. Multiple such sets of plates may be used to form an enclosure for a device that thermally insulates the device from ambient.

摘要： Aspects of methods and systems to reduce degradation of a fuel cell (110) during start-up and shut-down cycles are disclosed. An anode exhaust stream (201′) is periodically directed via fluid communication through an oxygen capture media (86). After shut-down of the fuel cell and before or during start-up said media (86) removes oxygen in the anode exhaust stream. Periodically, heating the oxygen capture media (86) is employed to purge the oxygen collected and regenerate the media.

摘要： The disclosure relates to an unmanned aerial vehicle, wherein a fuel cell system component provides a structural component of the vehicle. In some instances propulsion modules affixed to wings are oriented so as to provide airflow to plates of a fuel cell via air inlets for each fuel cell provided at the forward surface of each wing, a fuel cell system component forming a portion of the body and wherein the air inlets are unblocked during flight, each propulsion module is configured to provide air as an oxidant to a fuel cell via the air inlets.

摘要： Separator plates (108; 300; 400; 410) for fuel cell assemblies have a first edge (110, 310) and a second, opposing edge (111, 311). The fuel cell separator plates define a series of airflow channels (112, 113, 312, 313, 401, 411) extending longitudinally between the first and second edges. The airflow channels can be non-linear airflow channels formed from a linked series of bumps (320) opposite to corresponding recesses (321) in the facing channel walls. The linked series of bumps and recesses can run the entire channel length. The linked series of bumps and recesses can be formed as a sinusoidal wave having an amplitude and a frequency.
