A protection system (16) intended to protect, against electrical faults, an electrical system being supplied with electrical energy from a fuel cell (12). The fuel cell (12) is supplied by dihydrogen (111) and the protection system (16) comprises: a current sensor (161) configured to measure a current intensity level at output of the fuel cell (12), a controller (162) configured to compare the measured current intensity level with a predefined intensity threshold or with a predefined current profile, and means for controlling supply of the dihydrogen (111). When the measured current intensity level is higher than the predefined intensity threshold or matches the predefined current profile, the controller (162) is configured to send shutting instructions to the means for controlling supply of the dihydrogen (111), which stop supply of dihydrogen (111) to the fuel cell (12) upon reception of the shutting instructions. Thus, prompt reaction to electrical faults, such as short-circuits, is provided at low cost in terms of size and weight.
