China Harbin Institute of Technology research team independently developed a successful Kening temperature solid oxide fuel cell unit in greater substrate prepared breakthrough core technology. Reporter dell latitude e5400 battery September 17 the school was informed that they have developed the single and the power density reached the advanced international level, and the battery could be used to open the natural gas as fuel, thus reducing the effect of emissions and air pollution. The focus group is underway to further improve product performance and life, reduce costs, so industrialization.
The results obtained in solid oxide fuel cell (SOFC) in the low temperature, and its use of the strip casting method of sintering the largest gathering of the current size of 100mm x 100mm single cells, while more than 1000 ? the previous generation operating temperature to 750 ?, avoid electrode sintering quickly lead to cavities, electrodes and electrolyte reaction interface, the component of the battery dell latitude e5500 battery does not match the characteristics of thermal expansion, such as corrosion of metal connections FAQ.
The new results has recently passed appraisal Heilongjiang Science and Technology Organization.
Working group member told reporters, SOFC is the chemical energy of fuel directly into electrical energy electrochemically, known as cell fuel production fourth. Compared to the alkaline fuel cell, fuel cell phosphate fuel cells to cell membrane before the three generations of fuel cells and conventional combustion engine, the conversion SOFC with high efficiency, fuel, a wide applicability, low cost, energy saving, zero pollution, etc., Built-in battery efficiency dell latitude e5400 battery of electricity generation by more than 50%, thermal power, even for more than 80%.
Before working temperature SOFC R & D is about 1000 ?, and difficult to achieve high operating temperature of commercial applications, if the lower temperature will reduce the catalytic activity of electrode materials. The new results of this bottleneck completely broken.
Reporters also learned that this new fuel cell can use natural gas as fuel, not only the full use of Heilongjiang Province, the depth of natural gas resources, to effectively alleviate the contradiction between supply and power demand, but also reduces the process of producing electricity and exhaust carbon, nitrogen and sulfur to reduce global warming and air pollution. In particular, SOFC fuel gas by gasification combined steam and gas turbine power generation technology, integrated gasification, steam turbine, power generation gas turbine has the advantage of technology, Full use of carbon-based fuels, electricity generation, fuel cell technology to produce power based on the further development of hydrogen and capture of CO2 separation and recovery technology. Therefore, the results to improve the transition from coal resources of China Town to change the industry chain of coal is short, the status of low value-added of great practical importance.
