The invention relates to a method for operating a fuel cell, particularly for switching off a fuel cell. In order to switch off the fuel cell, the supply of the gas mixture comprising oxygen and nitrogen is interrupted, wherein the oxygen present at the cathode reacts with the protons present by means of conversion, and the residual oxygen content at the cathode side of the fuel cell is lowered in this manner. Due to the method according to the invention, the fuel cell may be better stored, wherein a defined low chemical potential is applied at both electrodes. |
