    摘要: A microvalve assembly (30) is integrated into a printed circuit board (PCB) substrate (31). An aperture (32) in the PCB substrate includes a closure member (33) extending into the aperture. A flexible fluid pipe (38) is disposed between the closure member and a closure edge (37) of the aperture. A displacement member (34) is coupled to the PCB and is configured for thermal actuation to displace the closure member so as to vary the cross-sectional profile of the flexible fluid pipe. The closure member may be a cantilever section of the PCB substrate. Displacement of the closure member to vary the cross-sectional profile of the flexible fluid pipe can occur entirely within the plane of the PCB substrate and movement of the displacement member to displace the closure member can also occur entirely within the plane of the PCB substrate, providing a very low profile of microvalve particularly suited for integration into a fuel cell stack (1).

    摘要: A gas connector comprising a gas outlet port; and a reconfigurable mating interface. The mating interface is configured to provide a first mating profile and a second mating profile. The first mating profile is configured for connecting the gas connector to a first type of electronic device and the second mating profile is configured for connecting the gas connector to a second, different, type of electronic device.

    摘要: A fuel cell stack assembly has a plurality of cells in a stack configuration. Each cell comprises a membrane-electrode assembly disposed between an anode flow plate and a cathode flow plate. A current collector plate is disposed at each end of the stack and a compression assembly maintains the stack under compression. At least one of the current collector plates is formed as a printed circuit board having a first face disposed against a cathode flow plate or an anode flow plate of an outermost cell in the stack and a second face opposite the first face. The first face includes an electrically conductive layer disposed on a substrate of the printed circuit board to serve as a stack current collector electrode. Electrical components such as temperature sensors can be mounted on the printed circuit board such that they lie in or adjacent to a flow channel extending along an adjacent face of the anode or cathode flow plate. The printed circuit board can provide laterally extending connection tabs for electrical connection to the current collector electrode and to the electrical components.

    摘要: A control valve for controlling the exhausting of a purge gas from a fuel cell assembly, comprising a valve body having a valve member therein moveable between a first position and a second position, an inlet port for receiving a purge gas from the fuel cell assembly and an outlet port for providing an outlet for the purge gas, the valve member configured to, in the first position, prevent purge gas from flowing between the inlet port and the outlet port and, in the second position, allow the flow of purge gas between the inlet port and the outlet port, the valve body including a drain port adapted and arranged in the valve body to allow liquid to drain out of the valve body, the drain port configured to close when the valve member is in the second position.

    摘要: A fuel cell power module is coupled to a fuel supply reactor module by way of an adaptor which includes some of the control elements for controlling reaction of reactants in the reactor module. The adaptor includes a housing and a first connection interface in the housing for detachably coupling the adaptor to a fuel cell power module fuel inlet port and a second connection interface in the housing for detachably coupling the adaptor to a reactor module fuel outlet port. A fluid line extends between the first connection interface and the second connection interface. The adaptor includes a motive unit of a flow control mechanism configured to provide motive power to a flow circuit of a reactor module when the reactor module is coupled to the adaptor. The adaptor enables a fuel cell power module to be interfaced with different types of reactor modules having different form factor and different control requirements.
