摘要： Presented are mobile charging stations for recharging electrified vehicles, methods for making/using such mobile charging stations, and parking facilities equipped with such mobile charging stations. A mobile charging station includes a frame with drive wheels and a prime mover operable to drive the wheels to propel the charging station. A hydrogen storage container and fuel cell are mounted to the frame. The fuel cell oxidizes hydrogen received from the storage container to generate electrical current. An electrical coupling mechanism connects the fuel cell to a battery pack of an electric-drive vehicle. A resident or remote controller is programmed to receive charge requests to recharge vehicles, and responsively determines path plan data for the mobile charging station. The controller commands the prime mover to propel the mobile charging station from the charger's origin to a charger destination, and enables the fuel cell to transmit electrical current to the vehicle.

摘要： A fuel cell system with reduced leakage and a method of assembling a fuel cell system. Bipolar plates within the system include reactant channels and coolant channels that are fluidly coupled to inlet and outlet flowpaths, all of which are formed within a coolant-engaging or reactant-engaging surface of the plate. One or more seals are also formed on the fluid-engaging surface to help reduce leakage by maintaining fluid isolation of the reactants and coolant as they flow through their respective channels and flowpaths that are defined between adjacently-placed plates. The seal—with its combination of in-plane and out-of-plane dimensions—forms a substantially hollow volume, into which a plug is placed to reduce the tendency of the seal to form a shunted flow of the coolant or reactant around the intended active area of the plate. A fluid port intersection is integrally formed with the seal and is formed to be fluidly cooperative with the volume, and is capable of accepting the introduction of a fluent precursor of the plug material such that upon curing, the precursor material forms a substantially rigid insert that continuously fills both the volume and intersection, thereby increasing the resistance of the plug to movement and the seal to shunted flow. In one form, the geometry of the fluent material injection site is such that it promotes plug anchoring within its intended location, while also providing a manufacturing aid to visually inspect for plug installation, as well as to serve as a bipolar plate stacking alignment locator and verification.

摘要： A torque generating system is described, and includes a fuel cell power device, a high-voltage battery, an electric drive unit, and a controller. The fuel cell power device has a non-linear power-temperature relationship that has a local temperature maxima at a first electric power level and a local temperature minima at a second electric power level. A first operating point of the fuel cell power device is less than the first electric power level, and a second operating point of the fuel cell power device is set at a third electric power level that is greater than the first electric power level, wherein the third electric power level generates a fuel cell temperature that is less than the local temperature maxima. The fuel cell power device is controlled to one of the first operating point or the second operating point to transfer electric power to the electric drive unit.
