Introduction: The fuel cell portable power supply is an independent small power generation device that combines the design of fuel cells and patented solid fuel solutions to provide users with reliable uninterrupted power supply while significantly reducing weight.

Technical characteristics: Fuel cell portable power supply, as a mobile power supply using clean energy technology, integrates the advantages of long-term uninterrupted operation of proton exchange membrane fuel cells with the advantages of high energy density, safety, non-toxicity, and ease of portability of sodium borohydride. Compared with traditional mobile power supplies, it has the following significant advantages:

1. High energy density: The energy density of the fuel used in fuel cell portable power supplies is 500Wh/kg, while the energy density of lithium batteries is 120Wh/kg. The weight of a fuel cell portable power supply that provides the same amount of electricity is only 1/2-1/3 of the moving weight of a lithium battery, making it convenient for users to carry.

2. Uninterruptible power supply: The fuel cell portable power supply only takes tens of seconds to replace the fuel cartridge to continuously supply power, and it does not take hours to recharge.

3. Safety and environmental protection: Sodium borohydride is a safe and non-toxic substance. There is no danger of burning and explosion like lithium batteries.

Application situation or application prospects: Application scope: Fuel cell portable power supply can greatly increase the power supply time while ensuring good portability. It can help users perform important tasks for a long time in field reconnaissance, emergency rescue, and disaster prevention without worrying about insufficient power supply to electronic equipment. problem. Therefore, the portable fuel cell power supply that is portable and capable of supplying power for a long time represents the future development direction of mobile power supply and can effectively solve the problem of insufficient power supply caused by the high frequency of use of mobile electronic products. It is particularly worth mentioning that this type of power supply is the first time that it has been established and developed in my country, and it is also a hot topic of research by various government, military, defense and other departments internationally.

Market prospects: With the rapid development of science and technology, electronic information technology has begun to be increasingly used in military equipment. Electronic and information-based police equipment not only facilitates the work of users, but also increases the demand for electricity. In particular, with the popularization of mobile electronic military equipment, its frequency of use is becoming higher and higher. In terms of power supply, problems that often suffer from insufficient power supply and fail to deal with them in a timely manner are troubling users almost at any time.

Therefore, the development of mobile power supplies with large capacity, long battery life and significantly reduced weight compared to lithium batteries will greatly expand the application range of mobile electronic products and help users improve work efficiency. At present, some companies in developed countries such as Europe and the United States, such as the United States, Germany, and Japan, have developed such products and received good market responses.

Benefit analysis: In some scenarios where long-term power supply is required, such as outdoor emergency rescue, field investigation, disaster prevention, etc., police officers need to use mobile electronic devices, such as life detectors, communication walkie-talkies, GPS, etc. for a long time. work. If you use lithium batteries to achieve long-term power life of these devices, you need to equip multiple groups of large-capacity lithium batteries. Multiple groups of large-capacity lithium batteries (with a total capacity of more than 1kWh) are expensive, heavy and inconvenient to carry, which is a big problem for people working outdoors. At the same time, since the lithium battery power supply takes several hours to recharge after each use, it is very troublesome, which also invisibly increases management costs.

The fuel cell portable power supply developed this time has the advantages of large capacity, light weight, and long-term continuous use, and can achieve long-term power supply at low cost.
