Abstract: The invention relates to antifreeze concentrates for cooling systems in fuel cell drives, which are used to produce ready-to-use aqueous cooling agent compositions having a maximum conductivity of 50 .mu.S/cm, based on alkylene glycols or the derivatives thereof, containing one or several five-membered heterocyclic compounds (azole derivatives) with 2 or 3 heteroatoms from the nitrogen and sulphur group which contain no or at the most one sulphur atom and which can include an aromatic or saturated six-membered fusion agent.

Abstract: A method for cooling combustion engines involves using a circulating coolant fluid which contains non-ionic corrosion inhibitors and is at least intermittently deionized. Independent claims are also included for (1) a device for cooling combustion engines, comprising a coolant circuit (14) which is in thermal contact with the engine (11), and a de-ionizing device (28) in the coolant circuit (2) a liquid-cooled internal combustion machine with combustion engine(s) and coolant circuit(s) as above.

Abstract: Aqueous coolant with good corrosion inhibition comprises a phthalic acid monoamide ammonium salt. Aqueous coolant comprises a phthalic acid monoamide ammonium salt of formula (I); R1 and R2 = H or 1-20C alkyl; and A+ = ammonium cation. Independent claims are included for: (1) a cooler protectant concentrate comprising (I); and (2) the use of (I) in aqueous coolants for combustion motors.
