    • 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.
    • 一种用于燃料电池的冷却剂组合物,包括(a)亚烷基二醇,(b)去离子水,和(c)含有三甲基甲硅烷基的化合物。 含有本发明组合物的三甲基甲硅烷基的化合物防止亚烷基二醇的氧化,因此酸的产生为700ppm以下。 此外,该化合物防止亚烷基二醇的氧化,从而抑制离子材料的产生,因此导电率(氧化/初始电导率之后的导电率)的变化率可以保持在40倍以下。 因此,本发明的燃料电池用冷却剂组合物,即使在冬天不冻结,也可以用作电导率为40μs/ cm以下的燃料电池驱动装置的冷却系统的冷却剂。
