Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen energy, in particular to a demonstration platform which can demonstrate the whole process of hydrogen production, hydrogen storage and hydrogen use. Background Art

[0002] Hydrogen energy is a secondary energy with great development prospects in the 21st century. Hydrogen energy will be an important way for my country's low-carbon energy development. Hydrogen energy has significant advantages such as low carbon, high efficiency, energy interconnection medium, energy storage, safety and controllability. It can be used in many fields such as industry, transportation, construction and electricity.

[0003] The application of hydrogen involves hydrogen production, storage and use. At present, some domestic universities and research institutes have carried out teaching and research on hydrogen energy technology. In order to learn the basic principles of hydrogen production, storage and use, some teaching aids are needed for students to watch.

[0004] For example, the Chinese utility model patent with application number 2012201029107 discloses a proton exchange membrane hydrogen and oxygen fuel cell experimental teaching aid. The device for producing hydrogen from water electrolysis is powered by a voltage-stabilized DC power supply, and the cathode and anode are separated by a cloth membrane. The proton exchange membrane hydrogen and oxygen fuel cell group is composed of three single fuel cells in series, with hydrogen and oxygen guide grooves that can overlap with each other as much as possible. A multimeter is used to measure the voltage between the battery voltage output terminals or between the guide plates to show whether the battery generates electricity and its size. It can be used to learn the structural principles of proton membrane hydrogen and oxygen fuel cells, and can also be used by middle school teachers and students to study and learn the chemical reaction principles of water electrolysis and the structural principles of proton membrane hydrogen and oxygen fuel cells.

[0005] In addition, the Chinese invention patent with application number 2015106688950 discloses a wind-solar-hydrogen-electricity energy conversion demonstration system, which includes a wind power generation unit, a solar power generation unit, an electrolysis hydrogen production unit, a metal hydride hydrogen storage unit, a fuel cell and a load. After the wind / solar power generation unit generates electricity, the electrolysis hydrogen production unit converts the electrical energy into hydrogen energy, and the metal hydride hydrogen storage unit stores hydrogen. It can provide hydrogen for fuel cells to generate electricity as needed, and can also be used as an energy storage unit to achieve long-term loss-free storage and long-distance transportation of hydrogen energy.

[0006] However, there is no integrated demonstration platform on the market that can be used to show students the process of hydrogen production, storage and use, which cannot meet the needs of teaching.
