[0002] As a clean, efficient, green, and sustainable new energy source, hydrogen energy can help address energy crises and environmental pollution, and is a strategic energy development direction for humanity. With its abundant resources, high energy density, and clean, pollution-free properties, hydrogen energy's development and utilization are receiving unprecedented attention in today's climate of green development.

[0003] With the rapid development of the hydrogen energy industry, hydrogen energy is gradually entering people's lives. Various hydrogen-powered vehicles, hydrogen-powered drones, and hydrogen-powered power sources are changing people's lives. However, the limitations of hydrogen energy are becoming increasingly apparent.

[0004] The traditional hydrogen energy industry chain currently consists of hydrogen production plants, transportation, storage, hydrogen refueling stations, hydrogen storage tanks, and hydrogen equipment. On the one hand, how to obtain hydrogen on a large scale, cheaply, and pollution-free remains a common concern for scientists worldwide. On the other hand, since hydrogen is highly susceptible to vaporization, ignition, and explosion, properly addressing the storage and transportation of hydrogen energy has become a key to hydrogen energy development. Hydrogen storage tanks, as the most commonly used, present two pain points for ordinary users. First, the high pressure inside the tanks, coupled with the dangers of hydrogen, necessitates storage and transportation by professionally qualified organizations. Second, as a new energy source, hydrogen is expensive, and infrastructure such as hydrogen refueling stations is underdeveloped, often leading to hydrogen shortages.

[0005] Mobile hydrogen refueling machines are a type of hydrogen refueling method designed to meet the needs of small-scale refueling in different locations. They have the advantages of high mobility and ease of use. At present, the sources of hydrogen used in mobile hydrogen refueling machines mainly include high-pressure hydrogen storage tanks, water electrolysis hydrogen production, methanol cracking hydrogen production, and solid-state hydrogen storage material hydrogen release, each with its own advantages and disadvantages.

[0006] Based on this, the present invention proposes for the first time the combination of instant hydrogen production technology based on solid-state hydrolysis hydrogen production materials and a mobile hydrogen refueling machine to develop a self-sufficient mobile hydrogen filling equipment. This equipment can give full play to the advantages of instant hydrogen production technology such as low pressure, high energy density, low energy consumption, and convenient storage and transportation, and meet the small-scale hydrogen refueling needs in different occasions.

The cooling unit 3 includes a heat exchanger 301. The heat exchanger 301 has a fan group 302. The heat exchanger 301 is connected to the gas purification unit 6 through an air pipe. The gas purification unit 6 includes a dryer 601. A water vapor separator 602 is provided on the air pipe between the dryer 601 and the heat exchanger 301.

The water separated by the water vapor separator 602 flows back to the water tank 501 through the water pipe and the return water port. The hydrogen enters the dryer 601 through the air pipe for drying. The dried hydrogen enters the pressurization module 7 through the air pipe and the output valve 603, and the hydrogen is injected into the gas cylinder for storage.
