摘要： A bipolar plate assembly for a fuel cell includes a cathode plate disposed adjacent an anode plate. The cathode and anode plates are formed having a first thickness of a low contact resistance, high corrosion resistance material by a deposition process. The first and second unipolar plates are formed on a removable substrate, and a first perimeter of the first unipolar plate is welded to a second perimeter of the second unipolar plate to form a hermetically sealed coolant flow path.

摘要： A method for fabricating a radiation-cured structure is provided. The method includes the steps of providing a first radiation-sensitive material and applying a second radiation-sensitive material to the first radiation-sensitive material. The first radiation-sensitive material has a first sensitivity. The second radiation-sensitive material has a second sensitivity different from the first sensitivity. At least one mask is placed between at least one radiation source and the first and second radiation-sensitive materials. The mask has a plurality of substantially radiation-transparent apertures. The first and second radiation-sensitive materials are then exposed to a plurality of radiation beams through the radiation-transparent apertures in the mask to form a first construct in the first radiation-sensitive material and a second construct in the second radiation-sensitive material. The first construct and the second construct cooperate to form the radiation-cured structure.

摘要： A seal structure is disclosed for forming a substantially fluid tight seal between a UEA and a plate of a fuel cell system, the seal structure including a sealing member formed in one fuel cell plate, a seal support adapted to span feed area channels in an adjacent fuel cell plate, and a seal adapted to cooperate with a UEA disposed between the fuel cell plates, the sealing member, and the seal support to form a substantially fluid tight seal between the UEA and the one fuel cell plate. The seal structure militates against a leakage of fluids from the fuel cell system, facilitates the maintenance of a velocity of a reactant flow in the fuel cell system, and a cost thereof is minimized.

摘要： A bipolar plate used in a fuel cell and a method of making a bipolar plate. The sheet is made from a ferritic or austenitic stainless steel, and defines an undulated surface pattern such that the patterned sheet may be formed into the bipolar plate. In one configuration, a stamping or related metal forming tool operation will further deform the patterned sheet into the bipolar plate shape such that the wall thickness is substantially uniform throughout the surface. In this way, there is a substantial reduction in stretching/thinning/necking at an intersection between bends and side walls that define the undulations of the pattern. In one form, the pattern defines a repeating serpentine shape. In a particular embodiment, the bends may include surface modifications to reduce the effects of sheet-to-tool misalignment.

摘要： An engine control system for a vehicle includes an exhaust gas recirculation (EGR) rate-estimation module and a control module. The EGR rate-estimation module receives a first signal indicating a first relative humidity of a flow of air and a second signal indicating a second relative humidity of a mixed flow of air and exhaust gas. The EGR rate-estimation module determines an estimated EGR rate based on the first relative humidity and the second relative humidity, wherein the estimated EGR rate corresponds to a flow rate of a flow of exhaust gas to an engine. The control module selectively adjusts an engine operating parameter based on the estimated EGR rate.
