Abstract:
The invention relates to a method for protecting a set of electrochemical cells incorporated into a fuel cell stack from corrosion during an operation for shutting down the fuel cell stack, which method comprises steps of: measuring the voltage across the terminals of each of the cells to be protected; when the voltage measured for a cell is above a protection threshold, discharging this cell into an electrical load; when the voltage measured for a cell is below said protection threshold, disconnecting this cell from the electrical load.
