Description

Technical Field

[0001] The present invention belongs to the technical field of hydrogen production power, and in particular relates to a high-efficiency methanol reforming hydrogen production power system and method. Background Art

[0002] With the increasing global emphasis on environmental protection and sustainable development, the search for clean and efficient energy alternatives has become an urgent need. Hydrogen, as a clean and efficient renewable energy source, is considered an ideal alternative to fossil fuels due to its pollution-free nature and high energy density. Against the backdrop of the "carbon peak and carbon neutrality" goals, the development of hydrogen energy has garnered widespread attention and support.

[0003] In terms of application, high-efficiency methanol reforming hydrogen production power systems have been widely used in mobile hydrogen production, energy supply, transportation, military and other fields. Especially with the application and promotion of hydrogen fuel cells, stable and reliable hydrogen sources have gradually become a key issue in hydrogen energy applications. High-efficiency methanol reforming hydrogen production power systems can provide fuel cells with a safe and stable hydrogen source, opening up the entire hydrogen energy industry chain.

[0004] During hydrogen production, the purity of the hydrogen must be ensured before it is introduced into the fuel cell, which necessitates the use of a hydrogen purification device. During operation, cooling is generally achieved through gas exchange, but this operation fails to remove gaseous water, resulting in high humidity in the shell over a long period of time. High humidity in the introduced gas will only worsen the situation, and conventional gas introduction methods are not efficient enough for cooling. Therefore, a high-efficiency methanol reforming hydrogen production power system and method are proposed. Summary of the Invention

[0005] The present invention provides a high-efficiency methanol reforming hydrogen production power system and method, which aims to solve the problem that during operation, cooling is generally achieved through gas exchange. Such operation cannot remove gaseous water, resulting in high humidity in the shell for a long time. If the humidity of the introduced gas is high, the situation will be made worse. In addition, the general gas introduction method is not efficient enough for cooling.
