    摘要： A connector system is provided for facilitating electrically connecting to a fuel cell stack. The connector system includes a receptacle within the fuel cell stack, a circuit board, and a connector electrically connected to and extending from the circuit board. The receptacle is configured to facilitate electrically connecting to the fuel cell stack, and the connector is receivable within the receptacle for electrically connecting the circuit board to the fuel cell stack. The connector is elastically deformable to facilitate operative positioning of the connector within the receptacle, and to facilitate an interference fit of the connector within the receptacle against a surface defining, at least in part, the receptacle to secure the connector within the receptacle, with the connector electrically connected to a fuel cell plate of the fuel cell stack.

    摘要： A connector system for use in connecting a fuel cell plate to an electrical device includes first arms elastically deformable toward each other to allow an insertion of the first arms into a first slot of a fuel cell plate and elastically returnable to provide a force against a surface of the fuel cell plate to hold the arms against the fuel cell plate, and second arms elastically deformable toward each other to allow an insertion of the second arms into a second slot of an electrical device and elastically returnable to provide a force against a surface of the electrical device to hold the arms against the electrical device. The first arms are connected to the second arms at intersecting points allowing movement of the first arms relative to the second arms.

    摘要： A fuel cell system includes a membrane electrode assembly, a first plate separator and a second plate separator on opposite sides of the membrane electrode assembly. The first plate separator and the second plate separator have exterior ends away from the membrane electrode assembly. A first gas diffusion layer is located between the first plate separator and the membrane electrode assembly. A second gas diffusion layer is located between the second plate separator and the membrane electrode assembly. The sub-gasket extends from the membrane electrode assembly laterally toward at least one of the exterior ends. A first seal is located between the first plate separator and the sub-gasket. A conductive trace is attached to the sub-gasket and extends on the sub-gasket from an exterior side of the first seal to a location on an interior side of the first seal.

    摘要： A fuel cell system includes a first electrically non-conductive sheet portion having a coolant flow layer in an opening thereof, a first non-stamped, flat, metal separator on a first side of the coolant flow layer and a second non-stamped, flat, metal separator on a second side of the coolant flow layer opposite the first separator. A membrane is received in an opening of a second electrically non-conductive sheet portion. Gas diffusion layers are located on opposite sides of the membrane. The gas diffusion layers have channels open toward the first non-stamped, flat, metal separator or the second non-stamped, flat, metal separator to allow flow of an oxidant and/or fuel therethrough.

    摘要： A fuel cell system includes a first fluid flow plate including a first plurality of first channels for flow of an oxidant or a fuel. The plurality of first channel has first channel cross-sectional flow areas. A second fluid flow plate includes a second plurality of second channels for flow of an oxidant or a fuel. The plurality of second channels has second channel cross-sectional flow areas. A membrane electrode assembly is located between the first plate and the second plate. The first flow plate includes a passage for a flow of a fluid entirely on a seam side of the first flow plate as the first plurality of first channels. The passage has a cross-sectional area for flow of the fluid smaller than the first channel cross-sectional flow area.

    摘要： A fuel cell system includes a fuel cell stack and a reactant temperature conditioner. The conditioner includes a fuel inlet for receiving fuel from a fuel source and an oxidant inlet for receiving oxidant from an oxidant source. The conditioner is configured to transfer heat energy from the oxidant to the fuel to arrive at a conditioned oxidant and a conditioned fuel. The conditioner has a fuel outlet coupled to the fuel cell stack to allow flow of the conditioned fuel to the fuel cell stack and an oxidant outlet to allow flow of the conditioned oxidant to the fuel cell stack.

    摘要： A control algorithm for operating an integrated fuel cell system includes the following steps: determining whether a power output of a fuel cell is within a first predetermined range of an electrical load coupled to the fuel cell; lowering a reactant flow to the fuel cell when the power output is within the first predetermined range; detecting an increase of the electrical load; determining whether the increase exceeds a second predetermined range; and increasing a reactant flow to the fuel cell when the increase exceeds the second predetermined range.
