20120015283 | COMPOSITE GASKET FOR FUEL CELL STACK - A composite gasket to provide sealing and to control a swelling of at least a plurality of gas diffusion layers in a fuel cell includes a first incompressible layer provided near an anode flow field, a second incompressible layer provided near a cathode flow field. Further, the composite gasket includes a first elastomeric layer provided in between the first incompressible layer and the anode flow field and a second elastomeric layer provided between the second incompressible layer and the cathode flow field. | 01-19-2012 |
20120015280 | FLOW FIELD DESIGN FOR HIGH CURRENT FUEL CELL APPLICATIONS - A fuel cell includes an anode flow field plate having a flow field including a plurality of first lands and a plurality of first channels. Further, the fuel cell includes a cathode flow field plate having a flow field including a plurality of second lands and a plurality of second channels. A membrane electrode assembly is provided between the anode flow field plate and the cathode flow field plate. A width of each of the first channels is greater than a width of each of the second channels. | 01-19-2012 |
20120009495 | CONCENTRATION SENSOR USING AN ELECTROLYTIC CELL FOR AQUEOUS HYDROCARBON FUEL - A concentration sensor assembly for measuring a concentration of a aqueous hydrocarbon fuel to be supplied to a fuel cell stack, the assembly including a membrane electrode assembly having an anode, a cathode and an electrolyte membrane located between the anode and the cathode; a first monopolar flow field plate provided near the anode; a second monopolar flow field plate provided near the cathode; and a liquid gas separator. | 01-12-2012 |
20120009493 | COMPRESSION OF DIRECT METHANOL FUEL CELL STACKS WITH CATALYST COATED MEMBRANES AND MEMBRANE ELECTRODE ASSEMBLY - An apparatus to control a swelling of a catalyst coated membrane in a fuel cell includes an insulator layer provided at a perimeter of the fuel cell. The insulator layer has a plurality of insulator films and is secured to a flow field plate. The insulator layer has a less compressibility relative to a gasket used in the fuel cell. A method for controlling a swelling of a catalyst coated membrane in a fuel cell includes providing an insulator layer at a perimeter of each of fuel cells in a fuel cell stack. The fuel cell stack is compressed for a predetermined duration when the catalyst coated membrane is in a substantially dry state. Passage of fuel is allowed inside the fuel cell thereby facilitating the catalyst coated membrane to swell. A swollen catalyst coated membrane is allowed to contact the insulator layer. | 01-12-2012 |
20120005885 | APPARATUS AND METHOD FOR STACKING FUEL CELLS - An apparatus for fuel cell stacking includes an assembly jig having a base; an alignment assembly configured to be engaged with the base; and a compression assembly configured to be engaged with the alignment assembly. | 01-12-2012 |
