Abstract
A diagnostic system for a filter of a fuel cell includes a supply air duct in which a filter is disposed and in which a supply air flow toward the fuel cell can be guided. A diagnostic arrangement is disposed in the supply air duct after the filter in the flow direction of the supply air. The diagnostic arrangement permits the determination of a loading of the filter with at least one predefined substance. A vehicle having the system and a method for diagnosis of at least one filter of a fuel cell, are also provided.
Claims15
A diagnostic system for a filter of a fuel cell, the diagnostic system comprising:
- a supply air duct for guiding a supply air flow toward the fuel cell, the filter being disposed in said supply air duct;
- and
- a diagnostic arrangement disposed in said supply air duct after the filter in a flow direction of the supply air flow, said diagnostic arrangement configured to determine a loading of the filter with at least one predefined substance, said diagnostic arrangement including at least one indicator for indicating a loading of said at least one indicator with the at least one predefined substance;
- and
- at least one optical detector disposed in said supply air duct downstream of said diagnostic arrangement for optically recording an indicator reaction of said at least one indicator.
A method for diagnosis of at least one filter of a fuel cell, the method comprising:
- placing the filter and a diagnostic arrangement in a supply air duct for guiding a supply air flow toward the fuel cell;
- placing at least one optical detector in the supply air duct downstream of the diagnostic arrangement;
- locating the diagnostic arrangement in the supply air duct after the filter in a flow direction of the supply air flow;
- and
- diagnosing a loading of the filter with at least one predefined substance by monitoring a loading of the diagnostic arrangement with the at least one predefined substance;
- using at least one indicator of the diagnostic arrangement to indicate the loading of the at least one indicator with the at least one predefined substance;
- and
- using the at least one optical detector to optically record an indicator reaction of the at least one indicator.
