摘要： A duct interconnecting two channels in a fuel-cell flowfield is disclosed. In use, responsive to a flow velocity differential as between the two channels, reaction product water (in the case of a PEM fuel cell) is drawn from one channel to the other via the duct so as to aid in the removal of reaction product accumulations in one or the other of the channels. Each of the two channels may have an associated flow-velocity-increasing means (such as an in-line venturi) associated with each end of the duct. Depending on the location of the duct within a flowfield, the duct may also help to maintain a desired pressure drop and flow of reactant gas along each channel, which helps propel excess water along the channels, and, when the oxidant is oxygen in air, helps prevent localized oxygen depletion.

摘要： A solid-cage ambient-pressure PEM fuel cell stack having internal manifolds for the fuel gas and configured for accepting oxidant gas and cooling fluid via external manifolds/plena is disclosed. The fuel cell stack is contained in a solid cage comprised of a bottom end plate, a top end plate and four L-shaped struts. Each strut is attached at each end to a corner of the end plates so as to form a rigid rectangular parallelepiped cage, within which the fuel cell stack is contained. A pressure plate is disposed between the fuel cell stack and the top end plate. The pressure plate may be displace downwards, typically by way of an array of jack screws, so as to compress the fuel cell stack between the pressure plate and the bottom end plate. The vertical corners of the fuel cell stack engage the inside corners of the struts to further support the fuel cell stack.

摘要： A proton exchange membrane (PEM) fuel cell end plate assembly provides an axial direction electric lead on an end plate of the assembly, and minimizes the contact resistance between an end fluid separator plate of a fuel cell stack and a current collector of the assembly. The current collector comprises an electrically conductive flat plate and a solid member connected together. The member goes through an opening on the end plate and provides an axial direction electric lead from the fuel cell stack. Means are provided to firmly contact the current collector and the fluid separator plate to maintain good contact across the entire area between the two components. The means of firmly contacting include moulding or bonding the separator plate and current collector together, or applying pressure to the separator plate and current collector such that firm contact is maintained between the two components.

摘要： In solid polymer electrolyte fuel cells, a laminar flow of a dilute oxidant stream, for example air, may be disrupted by incorporating obstacles in the channels of an oxidant flow field. The laminar flow is changed to turbulent flow thereby enhancing the flow of oxygen to the membrane electrode assembly in the fuel cell and improving fuel cell performance.

摘要： This invention relates to a valve assembly for metal hydride hydrogen storage (MHHS) or chemical hydride hydrogen storage (CHHS) devices. The valve assembly comprises a body with an inlet connector for connecting to the MHHS or CHHS device, an outlet connector for connecting to an external device, a cavity in the body that is in gas communication with the inlet and outlet connectors, and a shut-off valve in the cavity that can be moved between an opened position that permits gas flow between the inlet and outlet connectors, and a closed position that denies said gas flow. The outlet connector has a first valve therein that is biased to remain closed when external pressure thereon is less than or equal to ambient pressure, thereby impeding at least atmospheric gas backflow into the cavity. The outlet connector can also have a second, one-way valve that permits gas flow out of the valve assembly only, as well as a bypass mechanism including a gas passage coupled to the cavity and upstream of the first and second valves, through which gas can be transmitted to the canister during charging.
