The invention relates to a method of protecting a fuel cell ( 12 ) comprising elementary cells, whereby said cell is supplying electric power in response to a power demand. Moreover, a booster circuit ( 30 ) is adapted to supply complementary electric power in order to assist the fuel cell. The inventive method comprises the following steps consisting in: determining a parameter that is representative of the minimum voltage from among the voltages at the terminals of each elementary cell; and controlling the complementary electric power supplied by the booster circuit, such that the minimum voltage remains above a determined threshold. The invention also relates to a fuel cell booster device. |
