Military power supply | High-energy power supplies for military applications
Military power supplyWith the continuous advancement of science and technology, modern warfare has entered the stage of high-tech warfare. The so-called high-tech war is a war in which at least one of the warring parties uses a large number of high-tech weapons and corresponding strategies and tactics. New weapons developed with high technology and existing weapons modified are called high-tech weapons. For example, precision-guided weapons, stealth aircraft, advanced C(U3)I systems, aerospace systems, anti-missile systems, electronic warfare systems, and night vision equipment used by multinational forces in the Gulf War. For the continuous charging of these electronic devices in the field environment, the modern army military power supply equipment has put forward higher requirements.
As a very common and widely used product, military power supply equipment has an important impact on the overall performance and quality of military electronic equipment. Traditional dry batteries and accumulators are cumbersome and not environmentally friendly, which is very inconvenient for military operations.
A few days ago, the US Department of Energy spent 34 million US dollars in the scientific and technological innovation projects, including four projects that are highly related to fuel cells. Many car companies, including BMW, have stated that they will officially release vehicles equipped with fuel cells after 2020.
A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Since the fuel cell converts the Gibbs free energy part of the chemical energy of the fuel into electrical energy through an electrochemical reaction, its conversion efficiency is very high; in addition, the fuel cell uses fuel and oxygen as raw materials; at the same time, there are no mechanical transmission parts, so There is no noise pollution and very few harmful gases are emitted. Therefore, from the perspective of saving energy and protecting the ecological environment, fuel cells are the most promising power generation technology.
The "fuel" in a fuel cell is different from the traditional fuels such as coal, oil, and natural gas that are common in life. As a new type of energy technology, fuel cell technology is matched with modern scientific and technological combat equipment. It has the advantages of high efficiency, cleanliness, economy and safety, and can help the upgrade and use of military weapons and equipment.
