1 is a conceptual diagram of a hydrogen peroxide circulation environment 100 according to an embodiment of the present disclosure. Referring to FIG. 1 , the environment 100 includes a charging station 110 , a fuel cell device 120 , and an exchanger 130 . The charging station 110 may produce and store hydrogen, which is the fuel of the fuel cell. The fuel cell device 120 may receive hydrogen, generate electricity from the hydrogen, and operate using it. The exchanger 130 is a device used to supply hydrogen from the charging station 110 to the fuel cell device 120 or to supply hydrogen peroxide from the fuel cell device 120 to the charging station 110 .

The filling station 110 includes a hydrogen peroxide storage tank 112 , a reformer 114 , an oxygen tank 116 and a hydrogen tank 118 . The hydrogen peroxide storage tank 112 stores hydrogen peroxide. The hydrogen peroxide storage tank 112 may be configured to maintain a constant temperature and/or pressure. To this end, a temperature measuring sensor (not shown) and/or a pressure sensor may be provided. Hydrogen peroxide is generally harmless and non-toxic to the human body, has no chemical reactivity with the atmosphere, has a low evaporation pressure (0.2 kPa at 30°C at 90wt. concentration) and high specific heat (2.52J/g·°C at 100wt.% concentration) Hydrogen peroxide maintains a liquid state at room temperature and can be stored for a long time in an appropriate container.Hydrogen peroxide stored in the hydrogen peroxide storage tank 112 is supplied to the reformer 114. The reformer 114 reforms hydrogen peroxide into oxygen and hydrogen. The reformer 114 may include a heater, a temperature sensor, a stirrer, a nozzle, etc. In one embodiment, the reformer 114 may reform hydrogen peroxide into oxygen and hydrogen using a catalyst. 110 is configured to provide oxygen and/or hydrogen to an external device, for example, the charging station 110 may sell oxygen or supply it to a device that uses hydrogen as a fuel cell.

In one embodiment, the reformer 114 may reform hydrogen peroxide into oxygen and hydrogen through a two-step process of decomposing hydrogen peroxide into water and oxygen and decomposing water into hydrogen and oxygen. The process of decomposing hydrogen peroxide into water and oxygen and decomposing water into hydrogen and oxygen is well known in the prior art, and thus a detailed description thereof will be omitted.

In one embodiment, the reformer 114 may generate hydrogen by using hydrogen peroxide as a material for autothermal reforming of hydrocarbons. For example, hydrogen peroxide may be adiabatically decomposed to produce oxygen and vaporized hydrogen peroxide, and the hydrocarbon may be reformed using this to produce hydrogen.

In one embodiment, the reformer 114 may directly reform hydrogen peroxide into oxygen and hydrogen. For example, a metal-free powder catalyst is added to a hydrogen peroxide solution containing phosphoric acid (H ₃ PO ₄ ) and irradiated with light to directly extract hydrogen from hydrogen peroxide. For example, it is possible to generate hydrogen from hydrogen peroxide by irradiating sunlight with graphitic carbon nitride loaded with graphene quantum dots (GQDs/gC ₃ N ₄ ) as a co-catalyst. In general, when a metal or metal oxide is used as a photocatalyst, hydrogen peroxide is decomposed into water and oxygen on the surface, but a catalyst that does not use a metal absorbs visible light and excites it to generate holes and excited electrons. Holes may oxidize hydrogen peroxide to generate oxygen, and excited electrons may reduce hydrogen ions to generate hydrogen gas.

For example, the hydrogen peroxide storage tank 122 includes a pump (not shown), and the pump operates under the control of the controller so that the hydrogen peroxide stored in the hydrogen peroxide storage tank 122 can be supplied to the charging station 110. .

The exchanger 130 is configured to supply hydrogen from the charging station 110 to the fuel cell device 120 , or to supply hydrogen peroxide from the fuel cell device 120 to the charging station 110 . For example, the exchanger 130 may be configured to measure the amount of hydrogen peroxide supplied to the charging station 110 and the amount of hydrogen supplied to the fuel cell device 120 . Exchanger 130 may be configured to display the price of hydrogen and hydrogen peroxide exchanged based on the measured amounts of hydrogen and hydrogen peroxide. In one embodiment, the exchanger 130 may include two nozzles (not shown). One nozzle may be a nozzle for supplying hydrogen, and the other nozzle may be a nozzle for supplying hydrogen peroxide. The two nozzles are independent, and the supply of hydrogen and the supply of hydrogen peroxide can be made independently, or alternatively, can be performed simultaneously.

In one embodiment, in order to supply hydrogen from the charging station 110 to the hydrogen tank 124 , the fuel cell device 120 may include a hydrogen fuel line (not shown). In addition, a line (not shown) for hydrogen peroxide may be included to supply hydrogen peroxide from the hydrogen peroxide storage tank 122 to the charging station 110 . The hydrogen fuel line and the line for hydrogen peroxide may be separate lines. The hydrogen fuel line and the line for hydrogen peroxide may be configured to open and close at the same time.
