20100035124 | HYBRID PARTICLE AND CORE-SHELL ELECTRODE STRUCTURE - A catalyst ink composition for a fuel cell electrode is provided. The catalyst ink composition includes: an ionomer; at least one solvent; a quantity of nanostructured thin film support cores; a catalyst formed from a precious metal, the catalyst coated onto the nanostructured thin film support cores; and a quantity of particles. The particles are configured to provide an electrode porosity that militates against excess water accumulation in the electrode formed from the ink composition upon a drying thereof. An electrode for a fuel cell and a method of fabricating the electrode with the catalyst ink composition are also provided. | 02-11-2010 |
20100081025 | MATERIAL DESIGN TO ENABLE HIGH MID-TEMPERATURE PERFORMANCE OF A FUEL CELL WITH ULTRATHIN ELECTRODES - A fuel cell including at least one of a hydrophilic interlayer and a flow field treated to impart hydrophilic properties is disclosed, wherein the hydrophilic interlayer and the treated flow field militate against water accumulation in ultrathin electrodes of the fuel cell, particularly for cool-start operating conditions (i.e. about 0° C. to about 60° C.). | 04-01-2010 |
20110143254 | FUEL CELL WITH LAYERED ELECTRODE - One embodiment includes at least one of the anode and cathode of a fuel cell comprises a first layer and a second layer in intimate contact with each other. Both the first layer and the second layer comprise a catalyst capable of catalyzing an electrochemical reaction of a reactant gas. The second layer has a higher porosity than the first layer. A membrane electrode assembly (MEA) based on the layered electrode configuration and a process of making a fuel cell are also described. | 06-16-2011 |
