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.
