Abstract: Use is claimed in the production of anti-freeze concentrates for fuel cell coolants based on 1,3-propanediol (optionally together with alkylene glycols or their derivatives) of 5-membered heterocyclic compounds (azoles) which have 2 or 3 sulfur or nitrogen atoms with a maximum of 1 S and which optionally also have an annelated aromatic or unsaturated 6-membered ring. An Independent claim is also included for such anti-freeze concentrates which are used in the production of ready-to-use 1,3- propanediol-based fuel cell coolants with maximum conductivity 50 microS/cm.

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: The invention relates to a method and a device for cooling an internal combustion engine. An aqueous, non-ionic coolant composition is used in a cooling circuit (14) of the internal combustion engine (11). In order to als o ensure long-lasting protection against corrosion for light metal components of the engine that come into contact with the coolant, e.g. components made of magnesium or magnesium alloys, the cooling circuit has at least one deionization device (28), for example, an ion exchanger, for the coolant.
