This invention provides novel fuel cell catalysts comprising new series of catalytically active thin-film metal alloys with low platinum concentration supported on nanostructured materials (nanoparticles). In certain embodiments, an integrated gas-diffusion/electrode/catalyst layer can be prepared by processing catalyst thin films and nanoparticales into gas-diffusion media such as Toray or SGL carbon fiber papers. The catalysts can be placed in contact with an electrolyte membrane for PEM fuel cell applications.

Novel systems for combinatorially screening an array of electrochemical cells are disclosed. The screening aparatus may comprise a system of electrodes and electrolytes common to each of the members of an electrochemical cell array. An electrochemical probe is used to supply a reactive fluid (or reactive species) to only one of the cells in the array at a time. The probe is configured to address each of the cells of the array individually, and to be chemically isolated from all of the other cells of the array. Thus, the cells of the array that are not being addressed by the probe are in a non-active condition. Such a system is capable of combinatorially screening a library of materials, including catalyst, electrode, and electrolyte materials, wherein each of the members of the library defines one of the cells of the array.

Novel green phosphors are disclosed having the comprise silicate-based compounds having the formula (Sr,A)(Si,A)(O,A):Eu, where Ais at least one divalent cation (a 2+ ion) including Mg, Ca, Ba, or Zn, or a combination of 1+ and 3+ cations; Ais a 3+, 4+, or 5+ cation, including at least one of B, Al, Ga, C, Ge, N, and P; Ais a 1−, 2−, or 3− anion, including F, Cl, Br, and S; and x is any value between 1. 5 and 2. 5, both inclusive. The formula is written to indicate that the Acation replaces Sr; the Acation replaces Si, and the Aanion replaces O. These green phosphors are configured to emit visible light having a peak emission wavelength greater than about 480 nm. They have applications in green illumination systems, red-green-blue backlighting systems, white LEDs, and plasma display panels (PDPs).
