Title: Method for storing a fuel cell at freezing temperature

Abstract: The method for storing a fuel cell comprises a first calibration phase of a reference membrane by nuclear magnetic resonance to obtain a progression curve of the maximum water load of the fuel cell membrane versus the temperature of the membrane, and a second calibration phase of a standard reference cell to obtain a relationship between the electrical resistance of the standard reference cell, the water load of its membrane and its temperature. The method then comprises a drying phase dependent on the two calibration phases.
