Method for purging a reactant chamber

Abstract

The invention relates to a method for purging a reactant chamber (A, K), in particular an anode chamber (A) and/or a cathode chamber (K), of a fuel cell system (100), having the steps of: determining a critical value (Pcritical) for an operating parameter (P) of the fuel cell system (100), said critical value characterizing a flooding of the reactant chamber (A, K), monitoring the operating parameter (P) to check if the critical value (Pcritical) has been reached, setting a threshold (Nmax) for a counter (N), in particular a time-dependent counter, monitoring the counter (N) to check if the threshold (Nmax) has been exceeded, and carrying out a purge process (DRAIN) of the reactant chamber (A, K) if the operating parameter (P) has reached the critical value (Pcritical) and if the counter (N) has reached the threshold (Nmax).
