  "textContent": "A method for controlling humidity in a fuel cell, wherein hydrogen is fed at a nominal pressure to the inlet of the cell, characterized in that at predetermined periodicity the following steps are repeated: instruction is given to open a hydrogen purge valve arranged on the outlet of the anode circuit; the pressure of hydrogen is measured at the inlet to the anode circuit of the cell, and the measured value is compared with a threshold pressure value; the purge valve is closed when the measured pressure is equal to or lower than the predetermined threshold pressure value; the opening time of the purge valve is measured; and the humidity level prevailing at the cathode of the cell is inferred therefrom.",
