Widely used in automobiles, electric vehicles, toy vehicles, power tools, emergency lighting, audio and video products, navigation, electronic toys, testing instruments, etc.
12V batteries have excellent performance, are easy to use and easy to charge. They are therefore favored by consumers, particularly in the automotive sector. Vehicles, 12V batteries are small in size and have large capacity and long range.
Use of water battery: Using only one water as raw material, as long as the specified amount of water is injected into the "water battery", it can produce electricity. Whether it is tap water, soy sauce, drinks or sea water, the battery can generate electricity.
Characteristics of water batteries: A water fuel cell of the same size can provide 8 times the energyelectrical energy from a methanol fuel cell, which means that a water fuel cell can be made very small to fit the size of a cell phone. Compared to lithium-ion batteries, water fuel cells have a similar charging time and several times greater capacity. Therefore, the standby time of mobile phones can be extended to several weeks or even one or two months, and the talk time can no longer be calculated in minutes. hours.
The main difference between water-hydrogen fuel cells and ordinary batteries is that dry cells and batteries are energy storage devices that store electrical energy and release it when there is an emergency. need, strictly speaking, water-hydrogen fuel cells are an energy; A generation device, such as a power plant, is an electrochemical energy production device that convertstitrates chemical energy directly into electrical energy.
Large power plants, whether hydroelectric, thermal or nuclear, send the electricity they produce to the grid, which then delivers it to users. However, due to the different loads of each electricity user, the electricity grid sometimes experiences peak peaks and sometimes low peaks, which can lead to power outages or voltage instability. In addition, about 70% of the combustion energy of traditional thermal power plants is consumed in huge equipment such as boilers and turbogenerators. During combustion, a large amount of energy is consumed and a large amount of harmful substances are emitted. Using water-hydrogen fuel cells to generate electricity directly converts the chemical energy of the fuel into electrical energy without burning. The conversion rate ofenergy can reach 60% to 80%. The device can also be less polluting and less noisy. big or small, and is very flexible.
The basic principle of water-hydrogen fuel cell power generation is to reform methanol to produce hydrogen power. The products of the water-hydrogen fuel cell are electricity and water. The specific reaction process is as follows: hydrogen on the battery anode is decomposed into protons and electrons under the action of a catalyst. Positively charged protons pass through the separator to the cathode, and negatively charged electrons flow in the external circuit. thus generating electrical energy. The oxygen ions present on the cathode combine with electrons and protons under the action of the catalyst to form water. A battery with a large number of fuel cells connected in series can generate enough electricity to conduire a car.
Characteristics of hydrogen and water fuel cells
(1) No pollution. Hydrogen fuel cells do not pollute the environment. Is electrochemical reaction, rather than combustion (gasoline, diesel) or energy storage (battery), the most typical traditional backup power solution? Combustion releases pollutants such as COx, NOx, SOx gases and dust. As mentioned above, water-hydrogen fuel cells only produce water and heat.
(2) Silent. The fuel cell operates quietly, with noise below 55 dB, which is below the level of normal conversation. This makes water-hydrogen fuel cells suitable for indoor installation or where there are exterior noise restrictions.
(3) High efficiency. The energy production efficiency of fuel cells is lowt reach more than 50%. This is determined by the conversion properties of fuel cells, which directly convert chemical energy into electrical energy without the need for intermediate conversion of thermal energy and machinery (generator).
With the development of hydrogen production technology, water-hydrogen fuel cells are getting closer and closer to our lives. In the near future, methanol will be delivered to thousands of homes through pipes like water, and each user will be connected to a water-hydrogen fuel cell and then connected to various electrical equipment. This will create a comfortable living environment for people and ease the heavy tasks of life. I hope that this new clean and convenient energy source - water-hydrogen fuel cells - will be used in people's daily lives as soon as possible.
