Abstract
The invention relates to a method for operating a fuel cell system (100), having a fuel cell stack (20) with a plurality of fuel cells (110) each having at least one cathode portion (K) and at least one anode portion (A), a compressor (10) for conveying air into the cathode portions (K), a pressure-sustaining valve (40), and a control device (50), the at least one cathode portion (K) being arranged downstream of and in fluid communication with the compressor (10) and upstream of and in fluid communication with the pressure-sustaining valve (40), the fuel cell system (100) having a high-pressure region (HDB) between the compressor (10) and the pressure-sustaining valve (40). The invention further relates to a control device (50) and to a fuel cell system (100).
