    摘要： A coolant composition for a fuel cell, including (a) an alkylene glycol, (b) deionized water, and (c) a compound containing a trimethylsilyl group. The compound containing a trimethylsilyl group of the composition of the present invention prevents the oxidation of the alkylene glycol, and thus the generation of an acid is 700 ppm or less. Additionally, the compound prevent the oxidation of the alkylene glycol, thereby inhibiting the generation of an ionic material, and thus the rate of change of electrical conductivity (conductivity after oxidation/initial conductivity) can be maintained to be 40 times or less. Therefore, the coolant composition for a fuel cell of the present invention can be used as a coolant for a cooling system of a fuel cell driving device with an electrical conductivity of 40 μs/cm or less even without being frozen in the winter.

    摘要： The present invention relates to a composition for an antifreeze liquid or a coolant. The present invention provides the composition for the antifreeze liquid or the coolant comprising: (a) a glycol-based antifreeze agent; (b) a cyclo hexane dicarboxylic acid; and (c) a non-reduced polyol. Generally, a mixture of mono- or dicarboxylic acid, which is used as a corrosion inhibitor agent, and an inorganic additive is prone to cavitation erosion and corrosion of gaps, but when a composition is comprised by using in parallel the cyclo hexane dicarboxylic acid and the non-reduced polyol, a synergy effect is created, thereby exhibiting a superior corrosion prevention effect with respect to cavitation erosion and corrosion of gaps inside a cooling apparatus.

    摘要： A composition for the antifireeze liquid or the coolant includes a cyclo hexane dicarboxylic acid, an azole- or thiazole-based inhibitor, and a metal from an element of group 2, group 5, group 6, or group 7. The composition of the present invention has increased corrosion resistance at a lower density by not containing organic additives, and has a better pH buffering property due to enhanced thermal oxidation stability at a high temperature. Even after a long-term operation for over 200000 km, the composition of the present invention maintains a metal corrosion resistance capability, the appearance of a water pump impeller and the inside of a radiator tube including aluminum remains decent, and the composition has a superior corrosion resistance effect with respect to internal metal parts even after an operational test, thereby allowing use of the composition for the antifreeze liquid or the coolant having a long life.
