According to an embodiment of the present disclosure, the self-contained hydrogen generation unit can be monitored through a mobile or a web, and can enable remote machine control, including the supply of water, the adjustment of a water level in the reserve tank, and the adjustment of an electrolyte concentration for water electrolysis, based on a result of the monitoring. Furthermore, power of the self-contained hydrogen generation unit can be remotely controlled in order to increase the lifespan of the battery and to be operated by introducing external power when the driving of water electrolysis in the fuel cell is stopped or when self-power production is stopped.

FIG. 3 is a flowchart for describing a method of managing the self-contained hydrogen power system for a smart farm according to an embodiment of the present disclosure.

A proposed method of managing the self-contained hydrogen power system for a smart farm includes step 310 of purifying, by the self-contained hydrogen generation unit, intake-water, generating clean hydrogen through water electrolysis, generating energy through the fuel cell by using the generated clean hydrogen, and storing the energy, and step 320 of receiving, by the farm environment control unit, energy for driving the plurality of sensors and the devices for producing aquatic products from the self-contained hydrogen generation unit and controlling an environment for producing aquatic products.

In step 310, the self-contained hydrogen generation unit purifies intake-water and generates clean hydrogen through water electrolysis. Energy is generated and stored through the fuel cell by using the generated clean hydrogen. The stored energy is used to additionally supply sufficient power to the water electrolysis device.
