Abstract
A method for identification of the fact of voltage sags in a fuel cell stack and diagnostics of the causes is considered. The method allows one to state the event as soon as possible after it happens. A procedure of classifying the causes of voltage sage, such as membrane dryout from the cathode side, membrane dryout from the anode side, air starvation, or high CO concentration, is constructed using a certain set of observations of the process variables.
