[0002] With the continuous development of hydrogen energy technology, methanol reforming reactors are being used more and more widely in the energy field. Methanol reforming technology can efficiently convert methanol into hydrogen, providing a clean hydrogen source for fuel cells and promoting the development of industries such as new energy vehicles.

[0003] A methanol reformer is a device that uses catalytic reforming technology to convert methanol-water solutions into hydrogen-rich gases. Specifically, the methanol reformer reacts methanol and water through catalysis to produce gases such as hydrogen, carbon dioxide, and carbon monoxide, with hydrogen being the main component. This device has important applications in fuel cell systems, especially in high-temperature fuel cells, where it can significantly reduce hydrogen production costs and improve the overall efficiency of the system.
