Embodiment approach

[0043] Preferred option one: if figure 2 As shown, the fast cold start drive unit 11 uses the hydrogen storage material assembly 7 to store hydrogen (pure hydrogen), which is used to heat up the combustion during the cold start of the methanol hydrogen generator system 1 and provide sufficient hydrogen at the initial stage of the client's startup. The hydrogen material components include hydrogen storage materials, high temperature and high pressure resistant shells and hydrogen output valves. Among them, there are many kinds of hydrogen storage materials. According to the storage state of hydrogen, they can be liquid hydrogen storage materials, high-pressure gaseous hydrogen storage materials and solid hydrogen storage materials. The stored hydrogen can be produced by the methanol hydrogen generator according to the present invention, or can also come from other alternative methods (such as high-pressure hydrogen cylinders).

Embodiment 1

[0051] In a preferred embodiment, the metal hydrogen storage material assembly is used as the cold start drive unit. It is calculated that 20.3 mol of hydrogen gas is consumed to meet the heat required by the fuel processor in the methanol hydrogen generator system to increase the temperature from 20°C to 250°C. That is, it needs to consume 40.6g of hydrogen. If the hydrogen flow rate is 1.4g / min for heating, it only takes 30 minutes to heat up to 250°C. If the client is a fuel cell with a stack power of 6kW as an example, from the moment the stack starts up until the methanol hydrogen generator can supply hydrogen, the stack needs to consume 3.1mol / min of hydrogen in terms of full power. A total of 113.3 mol of hydrogen is required from the start-up of the methanol hydrogen generator system until the methanol hydrogen generator can supply hydrogen. In this embodiment, the metal hydride hydrogen storage device HYM-100S / A (purchased from Beijing Haoyun Jinneng Technology Co., L...

Embodiment 2

[0053] In another preferred embodiment, the high-pressure hydrogen cylinder is used as the cold-start driving unit. After calculation and testing, it needs to consume 20.3 mol of hydrogen to meet the heat required by the fuel processor in the methanol hydrogen generator system to raise the temperature from 20°C to 250°C. , that is, it needs to consume 40.6g of hydrogen. If the hydrogen flow rate of 1.4g / min is used for heating, it only takes 30 minutes to heat up to 250°C. If the client is a fuel cell with a stack power of 6kW as an example, from the moment the stack starts up until the methanol hydrogen generator can supply hydrogen, the stack needs to consume 3.1mol / min of hydrogen in terms of full power. A total of 113.3 mol of hydrogen is required from the start-up of the methanol hydrogen generator system until the methanol hydrogen generator can supply hydrogen. Taking hydrogen storage in a hydrogen cylinder compressed to 15MPa as an example, only a container of less tha...

Description

technical field [0001] The invention relates to the field of hydrogen production, in particular to a rapid cold-start methanol hydrogen production machine system. Background technique [0002] Hydrogen energy is an important direction of the future energy development strategy and one of the most ideal energy sources, and a consensus has basically been formed internationally. Among all substances, hydrogen is the gas with the highest energy density. In the case of burning the same weight of coal, gasoline and hydrogen, hydrogen produces the most energy, and the product of its combustion is only water without any pollutants. Hydrogen reserves are large and widely distributed. For example, water contains 11% hydrogen, and soil contains about 1.5% hydrogen. Petroleum, coal, natural gas, animals and plants all contain hydrogen. [0003] With the popularization of people's understanding of hydrogen energy, the world's hydrogen production is increasing year by year, and the method...
