RAPID-RESPONSE SENSOR FOR CARBON MONOXIDE |
| Abstract: |
Species detection techniques are described based on
measurement of a dynamic response to an external stimulus. One
embodiment includes a voltage stimulus applied to a polymer electrolyte
fuel cell (PEFC), with the response to said stimulus used to measure CO
concentration on the anode catalyst. The principles of symbolic
dynamics, finite state machines or a simplified peak
response-to-asymptotic value measurement can be used to achieve a high
degree of precision for measuring CO concentrations. Using the
techniques of the present invention, CO poisoning of a fuel cell can be
monitored and diagnosed before reaching a critical condition, thereby
allowing early implementation of mitigation or graceful degradation
strategies. |
