| 摘要 |
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.
