Solid hydrogen fuel and method for stably supplying hydrogen

The present invention relates to a fuel composition and a hydrogen supply method thereof, and more particularly to a solid fuel composition capable of maintaining stable hydrogen evolution for a long period of time and a hydrogen supply method therefor.

The hydrogen supply device is an indispensable unit for providing a fuel cell system for providing fuel for power generation. Taking a hydrogen production system conventionally used in a hydrogen fuel cell as an example, if an aqueous solution of sodium borohydride (NaBH ₄ ) is used as a hydrogen source, a sodium borohydride aqueous solution (liquid fuel) can be pumped to the catalyst bed by a pump. After the hydrogen gas is released, the aqueous solution of sodium borate (NaBO ₂ ) is pumped away from the catalyst bed, and the hydrolysis reaction of sodium borohydride is accelerated by the catalytic action of the catalyst bed, so that hydrogen can be rapidly generated, and the chemical reaction formula (1) )as follows:

Since the chemical hydride water liberates hydrogen as an exothermic reaction, the temperature of the hydrogen supply device is susceptible to the exothermic heat of the reaction, and is not easily maintained at a constant temperature. As the water liberation hydrogen reaction continues, the temperature of the system or device continues to rise. When the temperature of the hydrogen evolution system rises, the rate of hydrogen evolution increases rapidly, which in turn causes the rate of hydrogen evolution to rise rapidly, and the stable rate of hydrogen evolution cannot be maintained. Figure 1 is a graphical representation of the relationship between hydrogen evolution rate and reaction temperature versus reaction time. It can be seen from Fig. 1 that the reaction temperature and the hydrogen evolution rate exhibit a high positive correlation.

Furthermore, fuel cells of different powers have corresponding hydrogen supply rates. If the hydrogen supply rate is too low, the fuel cells cannot reach their proper power. If the hydrogen supply rate is too high, hydrogen is wasted. Therefore, how to provide a stable hydrogen release rate to the fuel pool is an important issue.

At present, relevant knowledge has reached a stable control of hydrogen release flow through complex mechanical design. Please refer to the Republic of China Patent Application No. 096121493, entitled "Micro-type Hydrogen Generator". The hydrogen fuel used in this patent is also a solid hydride. The principle of hydrogen evolution is also to hydrolyze the solid hydride through the catalyst. This patent performs complex mechanism design for its container device in order to control hydrogen production and maintain a stable hydrogen release rate. However, the mechanical design of the device is too complicated, not only bulky, heavy, and expensive, but is not conducive to daily use and carrying in terms of physical and cost considerations.

The Applicant previously prepared a plastic solid hydrogen fuel by combining a catalyst and a solid hydride through a polymer substrate (Republic of China Application No. 98108205). Furthermore, the plastic solid hydrogen fuel can be further kneaded into various geometric shapes and appearance structures, placed in a suitable container, and a high and stable hydrogen release rate is produced after the water is filled in the container, as shown in Fig. 2. Shown, it shows a hydrogen evolution profile using a prior art plasticity solid hydrogen fuel. Among them, a pulverized mixture of 3 g of NaBH ₄ (solid chemical hydride) and 0.6 g of Co ²⁺ /IR-120 (solid catalyst, a cation exchange resin after chelation of cobalt ions) was uniformly dispersed in 2.5. In the gram of silicone rubber, the hydrogen release curve of Fig. 2 is obtained.

In addition, in order to solve the problem of liquid water leakage when the hydrogen supply device is in use, the applicant has previously proposed that all solid state chemical hydrogen discharge (Republic of China application number: 98112619) utilizes solid water to solve the problem of liquid water leakage. The water has a high specific heat characteristic, and can absorb a large amount of heat energy released by the hydrogen release reaction to maintain the temperature during the hydrogen discharge process. Please refer to FIG. 3, which shows a hydrogen release curve of a solid hydrogen fuel and solid water in the prior art. Among them, the solid hydrogen fuel used includes a pulverized mixture of 2 g of NaBH ₄ (solid chemical hydride) and 0.4 g of Co ²⁺ /IR-120 (solid catalyst), uniformly dispersed in 1.6 g of ruthenium rubber. Medium, while solid water is, for example, a hydrocolloid solid. However, since the water used for all-solid chemical hydrogen discharge is solid water, it is unable to absorb the heat released rapidly during the reaction, so that the hydrogen release rate cannot maintain a stable value, as shown in FIG.

The present invention relates to a fuel composition and a hydrogen supply method thereof, which mainly utilize phase-change materials to maintain a hydrogen supply device having the fuel composition for a long time, thereby controlling chemical hydrogenation. The temperature at which the water liberates hydrogen can maintain a stable hydrogen evolution for a long time when the water liberates hydrogen.

The phase change material is adjacent to a hydrogen evolution reaction of the solid hydrogen fuel, absorbs and stores the solid hydrogen fuel in a phase change manner to perform thermal energy generated by a hydrogen release reaction and maintains the reaction temperature to control the hydrogen release rate of the hydrogen evolution reaction. And maintain hydrogen flow.
