Advantages and key technologies of button cell battery cr2025
button cell battery cr2025 are devices that directly convert the chemical energy of fuel into electrical energy. It is a very promising clean and efficient way of generating electricity, and is known as the distributed power source of the 21st century. The working principle of button cell battery cr2025 is similar to the reverse process of water electrolysis. Hydrogen-based fuel is fed into the anode of the fuel cell (the negative electrode of the power source) and converted into hydrogen ions. Oxygen in the air is fed into the cathode of the fuel cell (the positive electrode of the power source). Negative oxygen ions reach the anode through the ion-conducting electrolyte between the two electrodes and combine with hydrogen ions to form water, and the external circuit forms an electric current.
Usually, a complete fuel cell power generation system consists of a cell stack, a fuel supply system, an air supply system, a cooling system, a power electronic converter, a protection and control and instrumentation system. Among them, the cell stack is the core. Low-temperature button cell battery cr2025 should also be equipped with a fuel reformer (also known as a fuel reformer). High-temperature button cell battery cr2025 have an internal reforming function and do not need to be equipped with a reformer.
Phosphoric acid button cell battery cr2025 (PAFC) are currently mature and commercialized button cell battery cr2025. Now we can produce various equipment such as large-capacity pressurized 11MW equipment and portable 250kW equipment. The molten carbonate cell (MCFC) of the second-generation fuel cell works at high temperature (600-700℃), and the reforming reaction can be carried out internally, which can be used for large-scale power generation. Now, megawatt-level verification tests are being carried out. Solid electrolyte fuel cell (SOFC) is called the third-generation fuel cell. Since the electrolyte is a solid electrolyte such as zirconium oxide, it can be used for coal-based fuel power generation in the future. Proton exchange membrane fuel cell is the most promising power source for electric vehicles. button cell battery cr2025 have the following advantages:
1) It has high efficiency. The theoretical power generation efficiency of hydrogen-based button cell battery cr2025 can reach 100%. The actual efficiency of molten carbonate button cell battery cr2025 can reach 58.4%. Through the comprehensive utilization of heat energy through cogeneration or combined cycle, the comprehensive thermal efficiency of button cell battery cr2025 is expected to reach more than 80%. The power generation efficiency of button cell battery cr2025 has basically nothing to do with scale, and small equipment can also achieve high efficiency.
2) In hot standby mode, button cell battery cr2025 have a very strong ability to follow load changes, and can follow 50% load changes within 1 second.
3) Low noise; can achieve practical zero emissions; save water.
4) Short installation period, flexible installation location, can save the construction of new transmission and distribution systems.
The current obstacle to the large-scale application of button cell battery cr2025 is the high cost, and it will take some time to compete with conventional power generation methods in terms of economy. The key technology of button cell battery cr2025 involves projects related to commercialization such as battery performance, life, large-scale, price, etc., and mainly involves new electrolyte materials and catalysts. The loss and corrosion leakage of liquid electrolytes in molten carbonate cells (MCFCs) under high temperature conditions reduce the life of the battery, limiting the large-scale and practical application of MCFCs. It is necessary to solve the corrosion of battery constituent materials; changes in electrode pore structure cause battery performance to decline.
Solid oxide button cell battery cr2025 (SOFCs) use solid electrolytes and have high operating temperatures, which have special requirements for constituent materials and their processing. In order to obtain an electrolyte that is chemically stable and dense (gas does not pass through) at high temperatures, Y2O3 is added to zirconium oxide to generate yttrium-stabilized zirconium oxide. In order to reduce the operating temperature, the thickness of the electrolyte film should be reduced as much as possible. Electrolyte films are usually prepared by melt spraying, sintering and electrochemical evaporation coating.
The thickness of practical electrolyte membranes is 0.03-0.05 mm. The more advanced ones have reached 0.01 mm. In addition to having sufficient mechanical strength, such thin electrolyte ceramic materials must have a high degree of gas density, otherwise the performance of button cell battery cr2025 will be lost. The fuel electrode uses heat-resistant metal ceramics such as nickel zirconium. Nickel is also used as a catalyst for fuel reforming. The air electrode is in high-temperature oxidation during operation, and it is difficult to use general metals. Platinum has good stability, but it is expensive. To find alternative materials, electronic conductive ceramics can be used. In order to reduce the operating temperature, another important research direction is to find low-temperature proton conductive electrolytes. If the operating temperature can be reduced to below 700°C, the cost of SOFC can be greatly reduced.
