STAND ALONE ENERGY SYSTEM USING HYDROGEN ENERGY

摘要

A stand-alone energy system using hydrogen energy is provided to store hydrogen by using a water electrolysis unit when any spare energy is generated from a recycled energy power generation system, so that the hydrogen is subsequently used to produce electric powder in a fuel cell. A stand-alone energy system using hydrogen energy comprises a power generation unit(10), inverter(14), fuel cell(13), water electrolysis unit(11) and a hydrogen storage tank(12). The stand-alone energy system further comprises a DC wire(20) linked to each of the above parts and allowing the electric power generated in the power generation unit to be supplied to the inverter; an uninterruptible power supply unit(23) receiving the power from the DC wire and supplying the power source in itself to each part so that the part is driven; and a control unit(21) for controlling the operation and interruption of the water electrolysis unit and the fuel cell.
