Abstract
A fuel cell system comprises a fuel cell having an anode and a cathode, a fuel feed line connected to the anode, an oxidant feed line connected to the cathode and a cathode exhaust line. A water collecting unit is connected to the cathode exhaust line, and a cooling circuit comprising a radiator is configured to cool the fuel cell. A nozzle is connected to the water collecting unit and configured to spray water onto the radiator.
