20130280640 | COMPACT FUEL CELL SYSTEM - An example fuel cell system includes a fuel cell power plant and a tank providing a volume that is configured to hold a fuel cell fluid. The fuel cell power plant is at least partially disposed within the volume. | 10-24-2013 |
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 |
20140147770 | LOW PLATINUM LOAD ELECTRODE - An electrode for an electrochemical cell includes platinum catalysts, carbon support particles and an ionomer. The carbon support particles support the platinum catalysts, and the ionomer connects the platinum catalysts. The electrode has a platinum less than about 0.2 mg/cm | 05-29-2014 |
20140349201 | FUEL CELL ASSEMBLY AND METHOD OF CONTROL - An exemplary method includes of operating a fuel cell at a first power output level that includes a plurality of operation parameters. Each operation parameter has a value to satisfy a first power demand. A change between the first power demand and a second power demand is determined. At least a first one of the operation parameters is maintained at a value corresponding to the first power output level or at an intermediate value while at least a second one of the operation parameters is changed to a value corresponding to a second power output level to satisfy the second power demand. The first operation parameter is delayed from changing to a value corresponding to the second power output level until a predetermined criterion is met. | 11-27-2014 |
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 |
20150079487 | FUEL CELL WITH IMPURITY FILTERING - A system has a fuel cell with an anode, a membrane, and a cathode. A source of fuel passes along the anode and a source of an oxygen containing gas passes along the cathode. A downstream line captures fuel downstream of the anode and a separator separates impurities from the fuel on the downstream line, and recirculates fuel downstream of the separator for passage across the anode. A method of mixing air with an oxygen concentrated gas is also disclosed. | 03-19-2015 |
20150099204 | REGULATION OF A FUEL CELL ASSEMBLY - A fuel cell assembly according to an exemplary aspect of the present disclosure includes, among other things, a first fuel cell stack in series with a variable resistor and a second fuel cell stack in parallel with the first fuel cell stack and in series with a contactor. A resistance level of the variable resistor is adjusted in response to deactivating the contactor. | 04-09-2015 |
20150099205 | MANIFOLD FOR PLURAL FUEL CELL STACKS - An assembly has a plurality of fuel cell stacks with at least one wall. At least one manifold portion is provided outwardly of the at least one wall of each of the fuel cell stacks. The at least one manifold portion for a pair of the plurality of fuel cell stacks is on facing surfaces with an intermediate wall between the at least one of the manifold portions on the pair of the plurality of fuel cell stacks. A method of forming an assembly of a plurality of fuel cell stacks is also disclosed. | 04-09-2015 |
