1. An energy-independent water electrolysis fuel cell water cart system, comprising:
a front part where a steering wheel and front wheels are disposed;
a rear part where a seat and rear wheels are disposed;
a connection part connecting between the front part and the rear part;
an awning roof obtaining power necessary for initial water electrolysis treatment and sunlight energy to be used as reserve power through a solar panel disposed on the awning roof and blocking sunlight, wherein the awning roof is connected to the seat;
a water electrolysis unit performing water electrolysis treatment on supplied water by using the sunlight energy and supplying hydrogen gas, generated through the water electrolysis treatment, to an energy generation unit through refinement using an absorbent and storage, wherein the water electrolysis unit comprises:
a water electrolysis treatment unit generating clean hydrogen gas through hydrogen electrolysis using sunlight energy by using filtered and refined water;
a gas controller adjusting pressure of the hydrogen gas generated through the water electrolysis treatment and supplying the hydrogen gas;
a hydrogen refinement unit converting the generated hydrogen into high-purity clean hydrogen gas through a hydrogen refinement process using an absorbent; and
a hydrogen storage unit storing the refined hydrogen gas;
an energy generation unit including a fuel cell generating electricity energy by the fuel cell using the supplied hydrogen gas; and
an energy storage unit supplying the generated electricity energy as electric power for the energy-independent water electrolysis fuel cell water cart system, wherein the energy storage unit comprises a battery management system (BMS) and a battery and stores extra electricity in the battery so that driving is possible even without power supply without requiring separate energy charging;
wherein:
the awning roof is connected to the seat;
the water electrolysis treatment unit, the gas controller, the hydrogen refinement unit, and the hydrogen storage unit are disposed in the rear part under the seat;
the BMS and the battery are disposed in the front part;
the fuel cell is disposed in the connection part between the seat and the front part;
the energy-independent water electrolysis fuel cell water cart system is an open-sided cart; and
the open-sided cart operates energy-independently, without external power being supplied to the open sided cart, by:
using electric power from at least a portion of the sunlight energy obtained by the solar panel for initial operation of the water electrolysis treatment of the water electrolysis treatment unit; and
storing electric power from the remaining sunlight energy obtained by the solar panel and the remaining electric power generated by the fuel cell to the battery.
