20120244455 | FUEL CELL FUEL RECYCLE EJECTORS DISPOSED IN FUEL MANIFOLD | 09-27-2012 |
20130177830 | FUEL CELL ASSEMBLY SEALING ARRANGEMENT - An example seal assembly includes a first seal that is configured to be placed between a fuel cell manifold and a fuel cell stack. The first seal establishes a recessed area within a side of the first seal that faces the fuel cell stack. The fuel cell seal assembly further includes a second seal that is configured to be placed between the first seal and the fuel cell stack within the recessed area. An example method of sealing a fuel cell interface includes holding a first seal within a groove established within a manifold and holding a second seal within a recessed area established within the second seal. The method limits flow of a fuel cell fluid using a first seal and the second seal. | 07-11-2013 |
20130230789 | FUEL CELL ASSEMBLY WITH ANTI-CLOCKING FEATURES AT THE ENDS OF THE CELL STACK ASSEMBLY - An exemplary fuel cell assembly includes a cell stack having a plurality of cells. The cell stack has an outermost plate at each of two opposite ends of the cell stack. An end plate is adjacent the outermost plate at each of the opposite ends. A plurality of anti-rotation members at each of the opposite ends prevent relative movement between the outermost plates and the end plates. The anti-rotation members at each end are at least partially received into the end plate at the corresponding end. The anti-rotation members at each end are only partially received into the outermost plate at the corresponding end without extending through the outermost plate. | 09-05-2013 |

20130273448 | FREEZE TOLERANT FUEL CELL FUEL PRESSURE REGULATOR - A fuel pressure regulator unit is mounted on a manifold. The fuel pressure regulator unit includes a housing providing a fuel inlet passage, a regulated fuel outlet passage, a sense pressure passage, a recycle passage and a mixed fuel passage. A pressure regulator is provided in the housing and is arranged fluidly between the fuel inlet passage and the regulated fuel outlet passage. The sense passage fluidly interconnects the mixed fuel passage and the pressure regulator. The pressure regulator is configured to regulate the flow of fuel from the fuel inlet passage to regulated fuel passage in response to a pressure from the sense pressure passage. An ejector is arranged within the housing and fluidly between the regulated fuel outlet passage and the mixed fuel passage. An ejector is configured to receive recycled fuel from the recycle passage. | 10-17-2013 |
20130323623 | FUEL CELL FLUID CHANNELS - An example fuel cell assembly includes a plate having channels configured to facilitate movement of a fuel cell fluid near an area of active flow of fuel cell. The channels include portions having a varying depth that extend laterally outside of the area of active flow. | 12-05-2013 |
20130337363 | FUEL CELL COMPONENT WITH EMBEDDED POWER CONNECTOR - An exemplary fuel cell component includes a plate comprising an electrically conductive material. An electrical connector includes a first portion embedded in the plate. A second portion of the electrical connector extends from the plate. The second portion is configured to make an electrically conductive connection with another device. | 12-19-2013 |
20130344418 | FUEL CELL BONDING METHOD AND ARRANGEMENT - An example method of securing a bond film to a fuel cell component includes positioning the bond film adjacent the fuel cell component and melting the bond film using thermal energy from an injection molded seal. | 12-26-2013 |
20150030964 | METHOD OF MAKING A FUEL CELL COMPONENT HAVING AN INTERDIGITATED FLOW FIELD CONFIGURATION - According to an illustrative embodiment, a method of making a fuel cell component includes removing material from a first plurality of locations along at least one surface on a plate to simultaneously establish a plurality of first channels on the surface. Each first channel has a length between a first end near a first edge of the surface and a second end spaced from a second, opposite edge of the surface. Material is also removed from a second plurality of locations along the surface to simultaneously establish a plurality of second channels on the surface. Each second channel has a length beginning at a first end spaced from the first edge and a second end near the second edge. Material is also removed from the surface near the first ends of at least some of the first channels to simultaneously establish an inlet portion for directing a fluid into the corresponding first channels. | 01-29-2015 |
