System and method of sterilization

The invention relates to a sterilization system (10) having a sterilization chamber (12) configured to receive an item to be sterilized (15) and enable the sterilization thereof when heated to a temperature above 100 ° C a fuel cell (14) proton exchange membrane configured to operate at a temperature above 100 ° C, and a heat transfer circuit (16) configured to transmit to the enclosure (12) a heat by the battery (14). It also relates to a sterilization process in which extracts heat on a fuel cell (14) proton exchange membrane configured to operate at a temperature above 100 ° C, and transmits the heat to an enclosure of sterilization (12) configured to receive an item to be sterilized (15), so as to raise the temperature thereof above 100 ° C and thus allow the sterilization of item.
