TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The composition (C1) further comprises an inorganic base. The composition (C1) further comprises an electrocatalyst (up to 20%). Preferred Components: The perfluorinated sulfonic acid ionomer or hydrocarbon-based ionomer is a salt. The salt comprising a cation selected from sodium, potassium, lithium, iron, cesium, magnesium, cesium, tetrabutyl ammonium, tetramethyl ammonium, tetrapropyl ammonium and/or tetraethyl ammonium. The perfluorinated sulfonic acid ionomer or hydrocarbon-based ionomer is protonated. The perfluorinated sulfonic acid ionomer has an equivalent weight of less than or equal to 1100. The hydrocarbon-based ionomer has an equivalent weight of less than or equal to 1600. The inorganic base is tetrabutyl ammonium hydroxide. The electrocatalyst comprises platinum or platinum on carbon.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The polyol is selected from glycerol, ethylene glycol, propylene glycol, butanediol, butanetriol, pentanetriol, and/or hexanetriol (preferably glycerol).    TECHNOLOGY FOCUS - POLYMERS - Preferred Method: In the method (M1), the temperature is 140-210 degrees C. The method (M1) further involves the step of forming the dispersion into an electrode suitable for use in a fuel cell, sensor, or capacitor. The method (M1) is free from the step of freeze-drying the composition. Preferred Components: The hydrocarbon-based ionomer is selected from sulfonated poly(arylene ether sulfone), sulfonated poly(arylene ether ketone), sulfonated poly(arylene ether nitrile), sulfonated polyphenylene and/or sulfonated polyimide. EXAMPLE - A catalyst dispersion (test) for thin film electrodes was prepared as follows: 21.57 g of glycerol, 0.54 g of perfluorinated sulfonic acid (equivalent weight (EW)=1100) with the functional groups having been hydrolyzed to SO3Na form (solid content 2.5 wt. %), and the polymer itself being in the form of membrane (thickness of 50 micrometer), were placed in a 60 ml vial. The vial was heated in a convection oven at 250 degrees C for 3 hours to obtain dispersion. Then, the obtained Nafion (RTM: sulfonated tetrafluoroethylene based fluoropolymer-copolymer) dispersion (1 g) was mixed with 1 g of water, and 0.0625 g Pt/C in a small vial. An amount of tetrabutylammonium hydroxide (TBAOH) equal to a molar equivalent of the ionomer was added to convert the ionomer to a thermoplastic TBA+ form. The mixture was agitated with ultrasound to uniformly disperse the supported catalyst in the catalyst ink. Nafion dispersion in water/isopropanol was used as control. The test/control dispersion was evaluated for fuel cell durability measured using potential cycling test. The voltage drop (V) during potential cycling was determined after 1000 cycles. The voltage drop for test/control dispersion after 1000 cycles was 0.001/0.016 at 0.2 A/cm2.
