    The present invention relates to an electric energy management system for a fuel cell electric propulsion body. According to one embodiment of the present invention, the electric energy management system for a fuel cell electric propulsion body comprises: a fuel cell which generates electric energy and supplies the generated electric energy to a load unit of the electric propulsion body; a super capacitor which charges the electric energy generated by the fuel cell and supplies electric energy to the load unit of the electric propulsion body when needed; a battery included in a power source of the electric propulsion body along with the fuel cell and the super capacitor and, under the set conditions, supplying electric energy to the load unit of the electric propulsion body along with the fuel cell and the super capacitor; and an EMS unit which compares the volume of electric energy supplied from the fuel cell and the super capacitor with the volume of electric energy required by the load unit of the electric propulsion body, and determines the electric energy supply of the battery. The super capacitor takes charge of a sudden change in the load. The battery takes charge of the power demand exceeding the capacity of the fuel cell and the super capacitor and thus, can improve efficiency.
