    摘要： The present invention relates to a coolant composition for fuel cell coolant, comprised of sulfur containing alcohol or sulfur containing phenol having at least one sulfur atom per molecule, which effectively prevents increase of electric conductivity due to oxidation of its base component for a long time. The coolant composition when diluted with water to a predetermined concentration effectively suppresses increase of electric conductivity of the coolant and maintain fluctuation of electric conductivity within the range from 0 to 10 μS/cm so that power generation efficiency of the fuel cell may not be lowered.

    摘要： A glycol-based coolant composition which provides an excellent metal corrosion inhibition despite its low phosphorus content is disclosed. The glycol-based coolant composition contains: (A) 0.1-5.0% by weight of at least one ingredient selected from group A′ consisting of C6-C12 aliphatic dibasic acids and their alkali metal salts; (B) 0.1-10% by weight of at least one ingredient selected from group B′ consisting of alkyl benzoic acids and their alkali metal salts; (C) 0.001-0.1% by weight of at least one ingredient selected from group C′ consisting of strontium compounds and their alkali metal salts; and (D) 0.1-0.3% by weight of at least one ingredient selected from group D′ consisting of phosphoric acids and their alkali metal salts.
