    Abstract: A vehicle is disclosed that includes a hood defining at least one opening, and a vent that is positioned within the at least one opening. The vent is reconfigurable between a closed configuration, in which the vent substantially (if not entirely) prevents air flow through the at least one opening in the hood, and at least one open configuration, in which the vent allows air flow through the at least one opening in the hood. The vent includes an integrated shape memory material such that, upon actuation, the shape memory material deforms to thereby reconfigure the vent.

    Abstract: A membrane electrode assembly includes a membrane, a gas diffusion layer and a catalyst layer between the membrane and the gas diffusion layer. The catalyst layer comprises catalyst comprising active catalyst particles supported on support particles, a proton conducting ionomer and a phospholipid containing soluble oxygen. One method of preparation includes preparing a catalyst solution comprising a solvent and catalyst, adding proton conducting ionomer to the catalyst solution to form a catalyst ink, saturating a solution of solvent and a phospholipid with oxygen and mixing the saturated phospholipid with the catalyst ink.

    Abstract: A method of preparing shape-controlled alloy particles includes dissolving a solvent in a surfactant selected to inhibit particle growth; adding a noble metal precursor and a transition metal precursor to form a mixture; irradiating the mixture with a microwave under reflux for about thirty minutes or less at an irradiation temperature of between 185° C. and 195° C.; cooling the mixture; and drying the mixture at a temperature of between 55° C. and 65° C. to obtain shape-controlled alloy particles having a uniform shape, the shape dependent upon the surfactant used.

    Abstract: Methods of preparing a cathode for a fuel cell include growing nanotubes on a substrate, the nanotubes of a material that is electron conductive; aligning the nanotubes such that the nanotubes extend from the substrate with a free distal end opposite the substrate; and depositing an active catalyst particle on the free distal end of each of the nanotubes. A membrane electrode assembly includes a cathode comprising a layer of electron conducting nanotubes extending from the electrode membrane and aligned such that a free distal end of each electron conducting nanotube is closer to the gas diffusion layer than the electrode membrane; an active catalyst particle attached to the free distal end of each electron conducting nanotube, wherein a diameter of the active catalyst particle is greater than a diameter of a respective electron conducting nanotube; and ionomer between each active catalyst particle and the gas diffusion layer.

    Abstract: Embodiments of electrode assemblies and fuel cells having increased catalyst durability are provided. One embodiment of an electrode assembly for a fuel cell comprises a first catalyst layer adjacent an electrolyte membrane comprising first active catalyst particles supported on first support particles having a first support size and a second catalyst layer adjacent the first catalyst layer opposite the electrolyte membrane comprising second active catalyst particles supported on second support particles having a second support size. The first support particles are a non-carbon support.
