Abstract

Die Wirksamkeit eines Ionenfilters wird mithilfe von mindestens zwei Leitfähigkeitssensoren, die stromaufwärts und stromabwärts des Ionenfilters angeordnet sind, dadurch überwacht, dass aus ihren Messwerten eine charakteristische Größe bestimmt wird, die mit der Wirksamkeit des Ionenfilters korreliert, und bei deren Abweichen von einem vorgegebenen Wert oder Intervall ein Signal ausgegeben wird. Dadurch wird eine zustandsorientierte Instandhaltung, beispielsweise bei Anwendung in einem Kühlkreislauf eines Brennstoffzellensystems, ermöglicht.
