    Abstract: The invention relates to a method for deionising a cooling medium of a fuel cell (11), said cooling medium circulating in a cooling circuit (20). Said cooling medium is at least intermittently, but preferably continuously, electrochemically deionised. To this end, at least one electrodeionisation cell (23) is arranged in the cooling circuit, a concentrate flow (28) and a diluate flow (27) used as a cooling medium passing through said cell. The concentrate flow (28) can be part of a secondary cooling circuit.

    Abstract: A process is provided for the preparation of trialkyl orthocarboxylates by the electrochemical oxidation of alpha, beta-diketones or alpha, beta-hydroxyketones, the keto group being present in the form of a ketal group derived from C 1 - to C 4 -alkylalcohols and the hydroxyl group optionally being present in the form of an ether group derived from C 1 - to C 4 -alkylalcohols (ketals K), in the presence of C 1 - to C 4 -alcohols (alcohols A), the molar ratio of the ketals K to the alcohols A in the electrolyte being 0.2:1 to 10:1.

    Abstract: The fuel cell has at least two electrodes (2'), each with at least one gas feed (8) for a reaction gas and a liquid electrolyte (6). The gas feeds of the electrodes each have an inlet and are arranged perpendicularly to the direction of travel of the ions under load traveling through the electrode arrangement. The cell is an undivided fuel cell and the gas feeds have at least one outlet each.

    Abstract: The present invention relates to a process for the deionization of a cooling medium in a fuel cell (11) circulating in a cooling circuit (20), 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 (23), through which a diluate stream (27) serving as cooling medium and a concentrate stream (28) flow, is arranged in the cooling circuit. The concentrate stream (28) may be part of a secondary cooling circuit.
