Background
With the continuous consumption of non-renewable energy sources such as petroleum and coal, and the increasingly serious environmental pollution and greenhouse effect, all countries in the world strive to find renewable clean energy sources, including green energy sources such as wind energy, solar energy and hydrogen energy. Compared with wind energy and solar energy, hydrogen energy has the advantages of being free from regional environment and climate limitation, and easy to store and transport, and therefore receives more and more attention.
The industrial production of hydrogen mainly includes natural gas reforming and electrolytic water processes. The natural gas reforming method has the advantages of large-scale production and low cost; the electrolytic water method has the advantage of high hydrogen purity, but is relatively costly and not conducive to high-scale production. Both methods are methods in which hydrogen stored in a chemical substance is converted into hydrogen gas through a chemical reaction. Besides natural gas and water, formic acid, methanol and the like are excellent hydrogen storage substances and have the advantages of high hydrogen storage density and convenience in storage and transportation.
Hydrogen gas is used as a clean fuel, and chemical energy stored therein can be converted into electric energy by a hydrogen fuel cell. The technology is mature and industrialized, and has the advantages of high conversion efficiency and zero pollutant emission. Therefore, hydrogen is more and more popular with governments and investors as a clean energy source with great application prospects. However, hydrogen has the disadvantages of difficult compression, high storage pressure, flammability and explosiveness, and the direct utilization of hydrogen as an energy source has high cost and high potential safety hazard.
Based on the analysis, the patent designs a clean energy power supply system for converting chemical energy stored in clean fuel into electric energy according to the idea of step-by-step energy conversion. Taking methanol and water as examples (which have the advantages of low cost, high hydrogen storage density and convenient transportation and storage), according to the design of the patent, the power supply system combines hydrogen production and a hydrogen fuel cell, so that the organic combination of a small hydrogen production factory and a hydrogen fuel cell power generation device is realized, and a standby power supply or a long-term power supply can be provided for small electric facilities or devices such as families, automobiles and the like.

Specifically, in the present embodiment, as shown in fig. 1, the clean energy power supply system includes a fuel tank 1, a primary conversion system 2, a secondary conversion system 3, a power output system 4, and a control system 5. The fuel tank 1 is filled with liquid or gas fuel through an inlet on a material conveying pipeline 101, raw materials are conveyed to the primary conversion system 2 through a pipeline 102, and motors are arranged on the material conveying pipeline 101 and the first pipeline 102, so that the raw materials are automatically input into the fuel tank 1 and the primary conversion system 2. Alternatively, the fuel tank 1 is filled with fuel through a filler neck by a human power. If the fuel is gaseous, it is also possible to set the fuel tank 1 to a high pressure of a certain value so that there is a pressure difference between the fuel tank 1 and the primary conversion system 2, and then to use a flow valve to deliver the raw material from the fuel tank 1 to the primary conversion system 2 at a certain flow rate. The raw material fed from the fuel tank 1 is chemically reacted in the primary conversion system 2 to generate chemical substances different from the raw material stored in the fuel tank 1, and the generated chemical substances are liquids or gases, and generally by-products or impurities and poisons, which cannot be directly utilized by the secondary conversion system 3, are removed through separation and purification, thereby generating a high-purity product. The resulting high purity product is fed to the secondary conversion system 3 via a second line 201. If the product is liquid, a motor (not shown) is provided on the second line 201 to supply a flow rate of the liquid product to the secondary conversion system 3.

The pipelines 101 and 102 are provided with motors so that the methanol-water raw material is automatically fed into the methanol-water fuel tank 01 and the reforming hydrogen production apparatus 02. Alternatively, the methanol-water fuel tank 01 may be manually filled with methanol-water fuel through a filler port of the feed line 101. The raw material fed from the methanol-water fuel tank 01 undergoes a catalytic reforming reaction in the reforming hydrogen production apparatus 02 to produce hydrogen, and the produced hydrogen uses a palladium membrane to separate CO and CO from the hydrogen2And small amount of H which is not reacted completely2O and CH3OH is removed, thereby generating high purity hydrogen (99.99%). The resulting high-purity hydrogen gas is stored in a hydrogen storage tank (not shown) under pressure and then fed to the hydrogen fuel cell 03 through a line 201. This makes it possible to stabilize the pressure and also to automatically feed high-purity hydrogen gas from the hydrogen storage tank to the hydrogen fuel cell by utilizing the pressure difference between the hydrogen storage tank and the hydrogen fuel cell 03. In order to control the flow of hydrogen into the hydrogen fuel cell 03, a gas flow valve is provided on the line 201.

During the operation of the reforming hydrogen production device 02 and the hydrogen fuel cell 03, only CO is discharged from the reforming hydrogen production device 02 and the hydrogen fuel cell 032And a small amount of CO, thereby realizing the aim of cleaning and environmental protection of the power supply system. The electrical energy generated by the hydrogen fuel cell 03 is passed through the circuit 301 to the lithium battery/circuit 04. The lithium battery/circuit 04 supplies power to an external appliance or power device through the line 401. During the operation of the methanol-water fuel tank 01, the reforming hydrogen production device 02, the hydrogen fuel cell 03 and the lithium battery/circuit 04, the integrated circuit 05 monitors the amount of methanol-water fuel stored in the methanol-water fuel tank 01 through the control circuit 501. When the liquid level of the methanol water in the methanol water fuel tank 01 is lower than a certain amount and is lower than a warning value, the integrated circuit 05 gives an alarm and prompts to fill the methanol water fuel. If the amount of methanol water in the methanol-water fuel tank is further reduced, integrated circuit 5 automatically closes lines 102 and 201, and puts reforming hydrogen production device 02 and hydrogen fuel cell 03 on standby. The integrated circuit 05 controls the start-up and shut-down of the hydrogen reforming plant 02 and the hydrogen fuel cell 03 through a control line II 502 and a control line III 503 respectively, and monitors the operation of the hydrogen reforming plant 02 and the hydrogen fuel cell 03. The integrated circuit 05 monitors the operation and output of the lithium battery/circuit 04 via control line four 504. Furthermore, the electrical energy required by the electric motors arranged on the lines 101 and 201 can be provided by a renewable energy source, such as a solar cell. When the whole system is started, the electric energy stored by the lithium battery 04 or the external power supply can be used for providing the power supply required by the operation, and the power supply required by the operation can be provided by the electric energy generated by the system.
Specifically, in this embodiment, the methanol-water fuel tank 01 is a waterproof plastic or metal container for methanol, or a pipe or a base station connected to a methanol and water pipe. The reforming hydrogen production apparatus 02 converts the methanol water raw material into low-purity hydrogen gas, and the methanol water liquid raw material supplied from the target methanol water fuel tank and not directly usable by the hydrogen fuel cell 03 is processed into a raw material directly usable by the hydrogen fuel cell 03. The reforming hydrogen production device 02 has the reaction conditions of high temperature (300-400 ℃) and normal pressure, the catalyst is a solid catalyst, and the catalytic reaction belongs to heterogeneous catalytic reaction generated on a gas-solid interface. The hydrogen fuel cell 03 converts chemical energy stored in the high-purity hydrogen gas generated by the reforming hydrogen production apparatus 02 into electric energy.

Reformer 200 is connected to the hydrogen fuel cell by line 201 for providing hydrogen fuel gas to the hydrogen fuel cell. The heat sink 400 is used to cool the released internal heat of the hydrogen fuel cell, and may be water-cooled or air-cooled according to the power of the fuel cell: the hydrogen fuel cell 03 with high power and large heat generation adopts water cooling, and the hydrogen fuel cell 03 with low power and small heat generation adopts air cooling. The whole machine support structure is divided into 3 layers by a first partition plate 601 and a second partition plate 602, the lower layer is used for placing a fuel tank, the middle layer 502 is used for placing a methanol water reforming device, the upper layer 503 is used for placing a hydrogen fuel cell and a heat dissipation device, the whole machine is provided with a control panel (not marked in the figure) for controlling the on-off and setting of the whole machine, and a fixing device or wheels are arranged on a base of the whole machine.
Specifically, as shown in fig. 4, in embodiment 4 of this example, the hydrogen reforming machine is constituted by a combustion chamber 20, a reforming chamber 30, a purification chamber 40, and the like. Methanol-water fuel enters the preheating base and a coil (not marked) in the reforming chamber 30 from the two water inlet pipes respectively to be gasified into gas, and then enters a reaction tube in the reforming chamber to generate hydrogen with lower purity. The hydrogen with lower purity enters a purification chamber 40 to generate high-purity hydrogen (99.99%), wherein one part of the hydrogen flows back to a combustion chamber (for supplying fuel to the combustion chamber), and the other part of the hydrogen flows through a methanation reactor to further lead trace CO or CO in the gas to be processed2Conversion to CH4And then passed to the fuel cell.
