502030 battery

　　Foreign 502030 battery are developing rapidly. Domestic 502030 battery urgently need to break through the technical bottleneck.

　　A fuel cell is a power generation device that directly converts the chemical energy of fuel and oxidant into electrical energy through electrochemical reactions. It mainly consists of positive electrode, negative electrode, electrolyte and auxiliary equipment.

　　Developed countries have regarded the development of large-scale fuel cells as a key research project, and the business community has also invested heavily in the research and development of fuel cell technology. Many important results have been achieved, and fuel cells are about to replace traditional generators and internal combustion engines. It is widely used in power generation and automobiles.

　　The problem of industrial production of catalysts, a key material for fuel cells, has been overcome by a joint R&D team from the Hydrogen Fuel Cell Laboratory of Tsinghua University and a technology company in Wuhan. Currently, this catalyst has obtained 17 patents, with a production capacity of 1,200 grams per day, and the price is only half of imported products.

　　As the core material of fuel cells, catalysts’ comprehensive performance and localization are directly related to the core competitiveness of my country’s fuel cell technology and its industrialization prospects. However, relevant intellectual property rights have always been in the hands of a few developed countries in the West. The high cost of long-term dependence on imports of catalyst core materials has restricted the independent development of my country's hydrogen energy industry.

　　According to data from the "China Fuel Cell Industry Market Forecast and Investment Strategic Planning Analysis Report" by the Qianzhan Industry Research Institute, fuel cells are mainly divided into six types, of which three types: PAFC, DMFC, and PEMFC use platinum metal catalysts.

　　In 2015, Tsinghua University and Wuhan Himalaya Optoelectronics Technology Co., Ltd. carried out in-depth school-enterprise cooperation and jointly used Tsinghua University's catalyst preparation process to carry out mass production technology research on Pt/C catalysts. At present, the catalyst production capacity has reached a scale of 1,200 grams per day, which can meet the use of 40 36kW fuel cell stacks and has the conditions for large-scale industrial production. This series of achievements has completely broken the long-term monopoly of a few countries on this technology, and the price is only half of similar imported products.

　　Catalyst series products have been used in fuel cell stacks of the Chinese Academy of Sciences, universities and many fuel cell companies. By the end of this year, 1,000 hydrogen fuel cells will be produced using this catalyst.

　　Wang Cheng, leader of the research team and director of Tsinghua University's Hydrogen Fuel Cell Laboratory, said that the next step will be for the team to continue to improve the catalyst's various indicators and improve its tolerance to impurities such as sulfides and nitrogen oxides, paving the way for continuous localization of my country's fuel cells. Inject strong motivation.

　　Most problems in industrialization and commercialization can be attributed to cost, and fuel cells are no exception. In the past 10 years, cost control of fuel cells has been one of the most important goals of research institutions and industry.

　　Fuel cells are part of clean energy. Since their reaction process is a pollution-free water reaction, no pollutants are produced during the reaction process. The main pollutants come from the fuel, and there may be pollution such as nitrogen oxides. Compared with the air pollution caused by ordinary thermal power generation and the heavy metal pollution caused by traditional batteries, the degree of environmental pollution caused by fuel cells is far lower.

　　The potential of fuel cells with high efficiency, no pollution, short construction period, easy maintenance and low cost will trigger a green revolution of new energy and environmental protection in the 21st century. Nowadays, in North America, Japan and Europe, fuel cell power generation is rapidly entering the stage of industrial-scale application with a momentum of catching up. It will become the fourth generation power generation method in the 21st century after thermal power, hydropower and nuclear power. The rapid development of fuel cell technology abroad must attract our sufficient attention. Now it has become a subject that the energy and power industries have to face up to.
