摘要： A method may activate a fuel cell including a plurality of electrochemical cells in a stack, the fuel cell being intended to operate, during at least one nominal operating phase, as an electric generator. Such a method may include, during an activation phase by electrolysis, prior to the at least one nominal operating phase: electrically supplying the fuel cell by an external electric generator, the electric supply being configured to apply an activation voltage greater than the voltage of the cell in an open circuit (OCV); fluid supplying a humid gas fluid at a first electrode and/or a second electrodes. The humid gas may have a relative humidity (RH) such that 40%≤RH
