Abstract |
AB |
[DE] Die Erfindung betrifft ein Verfahren zur Bestimmung des Füllgrads oder der Güte eines mittels eines Speichermediums (12) Gase speichernden Katalysators (10), wobei die Änderung mindestens einer physikalischen Eigenschaft des mit dem Speichervorgang sich verändernden Speichermediums (12) gemessen wird und anhand dieser Ergebnisse der Füllgrad oder die Güte bestimmt wird.
[EN] The method involves measuring the change of at least one physical property of the storage material (12) which changes during the storage process. The degree of filling or quality is determined. The process is used to determine the degree of filling or quality of a substance of a storage material (12) gas storage catalyst (10). Preferred process: The change of complex electrical impedance is measured. Measuring the complex impedance occurs at one or more frequencies from frequency range between 0 Hz, i.e. direct voltage and upper frequency boundary at which the wavelength corresponding to measuring frequency is essentially smaller than dimensions of measuring apparatus. |
