TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The metal alkoxide comprises a titanium alkoxide or zirconium alkoxide. It is metal ethoxide, metal n-butoxide, metal isopropoxide, or metal n-propoxide. It is preferably titanium n-butoxide or zirconium n-propoxide. The orthosilicate is tetraethylorthosilicate. The solvent is ethanol in a molar ratio of ethanol to metal alkoxide of 5:1-53:1.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The sol-gel derived composite has a structure of (((Pt)a(RU)b(M)1-(a+b))1-d ((Ti-nyZrxSi1-x-y)(O1-eOH2e)z)d)q (C)r. A gelling agent facilitates the polymerizing step. After the polymerizing step, the inorganic gel is dried through heating the inorganic gel or removing the solvent from the inorganic gel. The inorganic gel is calcined.n = 3-4;x = 0-1;y = 0-1;x+y = greater than 0;z = (4(x+(1-x-y)) + n(y))/2;a = 0.01-1;b = 0-0.99;d = 0.05-0.95;e = 0-1;M = promoter element from Ni, Co, Fe, W, or Mo;C = at least one electrically conductive component;q = 5-90 wt.%; andr = 1-q.Preferred Property: The mixture has a pH of 1-2.

EXAMPLE - In an inert atmosphere drybox, 3.0957 g platinum tetrachloride was combined with 2.033 g ruthenium chloride hydrate and 800 ml of punctilious ethanol. A second solution was prepared by combining 3.1224 g titanium n-butoxide with 1.911 g tetraethylorthosilicate and 50 ml of punctilious ethanol. The second solution was added to the first solution with stirring. Then, 6 g Vulcan XC72R was added ca. 10 seconds later. After 5 minutes, 1.32 g water was added to the solution. The solution was stirred and blanketed with nitrogen. After about 72 hours, the material was dried at 100degreesC for 5 hours. The dried powder was reduced by first wetting 7 g catalyst powder with 20 g water. A 37.4869 g sodium boron tetrahydride in 14 M sodium hydroxide was contacted with the powder. The catalyst was prepared and 0.2158 g of the catalyst, 0.4065 g of aqueous Nation Ionomer Solution, and 5.3775 g water were milled for 30 minutes. The ink was coated onto carbon paper strips. The entire strip, 1 x 105.5 cm2, was heated in flowing hydrogen at 120degreesC for 1 hour prior to measurement.
