Additive formulation suitable for antistatic modification and improving the electrical conductivity of inanimate organic material

The invention relates to oil-in-water emulsions based on fatty alcohols and mono- or diesters of glycerol and the use thereof as antifoams or deaerators for aqueous compositions. The oil phase of the emulsions according to the invention consists to at least 95% by weight of the following constituents: a) 40 to 95% by weight, based on the total weight of the oil phase, of a mixture of at least two alcohols as component A, consisting of: a1) at least one alkanol having 12 to 30 carbon atoms as component A1, a2) at least one mono- or diester of glycerol with at least one fatty acid having 14 to 24 carbon atoms as component A2; b) 0.1 to 10% by weight, based on the total weight of the oil phase, of at least one further component B, which is selected from esters of C-C-alkanecarboxylic acids with polyglycerol, amides of C-C-alkanecarboxylic acids with alkylenediamines or oligoalkyleneamines, and esters of C-C-alkanecarboxylic acids with C-C-alkanols, and mixtures thereof, c) 4.9 to 50% by weight, based on the total weight of the oil phase, of at least one further component C, which is selected from organic substances which are liquid at 50&#xb0; C. and 1013 mbar, at atmospheric pressure have a boiling point above 200&#xb0; C., and at 25&#xb0; C. and 1013 mbar have a solubility in water of less than 0.1 g/l.

The present invention relates to a process for the deionization of a cooling medium in a fuel cell () circulating in a cooling circuit (), in which the cooling medium is subjected to at least intermittent, but preferably continuous, electrochemical deionization. To this end, at least one electrode deionization cell () , through which a diluate stream () serving as cooling medium and a concentrate stream () flow, is arranged in the cooling circuit. The concentrate stream () may be part of a secondary cooling circuit.
