According to the invention, there is provided seed and plants of the corn variety designated CV677156. The catalyst for a fuel cell comprises a fine particle of a metal represented by formula:PtxRuySizT1u wherein T1 represents at least one element selected from the group consisting of nickel, tungsten, vanadium, and molybdenum ; x=30 to 90 atomic %; y=0 to 50 atomic %; z=0. These devices also pass much of the incident light in the spectral range in which the device’s photoluminescent materials emit light, thereby greatly increasing the effective intensity of light available in the targeted 590-850 nm wavelength range. After tie bars interconnecting a plurality of leads have been cut, a package is subjected to heat treatment at a predetermined temperature. The high modulus material may be present in the trunk, branches, or both.
