摘要： Between adjacent MEA's is a bipolar plate assembly having a first sub-plate with a flow channel which is open to the anode side of the one of the MEA's. A second sub-plate has a flow channel which is open to the cathode side of the adjacent MEA. The sub-plates are nested together to form a coolant flow channel between the sub-plates. The coolant flow path has a height dimension wherein the distance between the adjacent MEA's is substantially unaffected by the height dimension of the coolant flow path. A method of manufacturing a bi-polar plate assembly includes forming a closed coolant flow channel between the sub-plates by nesting the sub-plates together. A method of operating a fuel cell includes passing the coolant through a flow path having a height dimension which is substantially aligned with the height dimension of the hydrogen flow path, the oxygen flow path, or both.

摘要： A technique for sealing the edges of fuel cells in a fuel cell stack that employs folding over the edge of bipolar plates. For those bipolar plates include both an anode side uni-polar plate and a cathode side uni-polar plate, one or both of the edges of the uni-polar plates can be folded. The folds can be provided to accommodate a tunnel between a flow header and flow channels in the active area, where the anode uni-polar plate is typically folded for the anode flow headers and the cathode uni-polar plate is typically folded for the cathode flow headers.

摘要： A device and method for operating a fuel cell system. The device includes a combustor that is configured to combine reactants used in the fuel cell in such a way as to produce an inert fluid used to inert electrodes within the fuel cell. The device also includes componentry to permit purging of the electrodes subsequent to their inerting. In one form, the combustor is of such thermal mass that heat generated by combustion of the reactants is substantially absorbed by the combustor such that recourse to supplemental cooling apparatus is not required. The combustor may also be configured to promote staged mixing and subsequent reaction of the fuel cell reactants to further limit excess heat generated by the reaction. While the device of the present invention is usable during any period of system operation, it is especially valuable for operational conditions associated with starting up and shutting down a fuel cell system to inhibit the formation of high voltage potentials that could otherwise damage fuel cell catalysts or catalyst supports.

摘要： A fuel processor for rapidly achieving operating temperature during startup. The fuel processor includes a reformer, a shift reactor, and a preferential oxidation reactor is provided for deriving hydrogen for use in creating electricity in a plurality of fuel cells. A first combustion heater system is coupled to at least one of the reformer, the shift reactor, and the preferential oxidation reactor to preheat the component during a rapid startup sequence. That is, the first combustion heater system is operable to produce thermal energy as a product of the combustion of air and fuel in the form of a first heated exhaust stream. This first heated exhaust stream is then used to heat the component directly or by using a heat exchanger type system. The first heated exhaust stream is also used by a second combustion device as a source of oxygen or diluent.

摘要： A flow translocator disposed within a conduit for transferring and separating laminar fluid flow during translocation of the fluid core to the outer perimeter of the conduit and the outer perimeter flow to the center of the conduit. The flow translocator includes a disk disposed transverse the length of a conduit and having an outer profile conforming to the inner profile of a conduit to form a sealed fit. Arrays of slots extend about the disk for simultaneously directing the fluid core to the inner profile of a conduit and the outer perimeter flow toward the fluid core. The slots are staggered to maintain separation of the fluid core and the outer perimeter fluid during translocation.

摘要： A gas turbine engine hot section component such as a turbine blade or vane having an airfoil is provided a non-film cooled portion of a heat transfer wall having a hot surface and a plurality of longitudinally extending micro-grooves disposed in the portion of the wall along the hot surface in a direction parallel to the direction of the hot gas flow. The depth of the micro-grooves is very small and on the order of magnitude of a predetermined laminar sublayer of a turbulent boundary layer. The grooves are sized so as to alter the boundary layer thickness near the leading edge of the airfoil to reduce heat transfer from the hot gas flow to the airfoil near the leading edge. In one embodiment the micro-grooves are about 0.001 inches deep and have a preferred depth range of from about 0.001 inches to 0.005 inches and which are square, rectangular, or triangular in cross-section and the micro-grooves are spaced about one width apart.

摘要： A system and method for reducing the corrosive effects of an air/hydrogen front in a fuel cell stack. The method includes shutting down the fuel cell stack and then initiating a hydrogen sustaining process where hydrogen is periodically injected into an anode side of the fuel cell stack while the stack is shut down for a predetermined period of time. The method determines that the hydrogen sustaining process has ended, and then purges the anode side and a cathode side of the fuel cell stack with air after the hydrogen sustaining process has ended and the stack is still shut-down.
