As a kind of electric vehicles, fuel cell cars are considered as human beings to solve problems of pollution and dependence on oil best car and the final program. Because the process of the fuel cell chemical reaction produces no harmful substances, only a small amount of water vapor emissions, while its high energy conversion efficiency than the engine Internal Combustion 2 to 3 times. Vehicles equipped with this battery as filling the hydrogen fuel can be kept running.
Besides cars, fuel cells in transportation, military, communications and other areas have prospects of general application. Developed countries have invested enormous resources in developing this technology, the national research units of fuel cells are up more than 30.
This includes the South China University of Technology.
Located in the central campus
Recently, the world’s largest proton exchange membrane fuel battery demonstration plants located in Guangzhou City University. It is designed by the University of South China for themselves, their own construction.
According to South China University of experts, based on basic engineering and multi-disciplinary forces, South China University of Technology won the 2004 major breakthroughs in key areas of Guangdong and Hong Kong this project the largest projects.
Project after project, the school key technologies for the creation of 7 focus groups, by Professor Shijun Liao, senior engineer Xia Jianwei, Dong xinf Professor, Professor Li Di, etc. 7 from experts from different disciplines. the group discussion to overcome various difficulties, after more than a thousand days and nights of hard work to solve the shape one by one industry expert headache technical problems of power, the formation of a step by step … …
Finally, the largest in the world of proton exchange membrane fuel cell demonstration plant is located in the South China University, University Park. Station covers an area of 2000 square meters, the walls red top blue shade of green trees, close to hear the voice of blowers, South China University of teachers and students hardly notice the campus added to a quiet powerhouse.

Why build a demonstration plant in the world’s largest? Shi-Jun Liao said: “The demonstrations of new technology to market a necessary step. Fuel cell technology, step by step amplification, involves many problems, only a certain capacity of the model, can the technology is mature and finally, marketing, construction demonstration power plant is to show the public the proton exchange membrane fuel cell of this new energy technologies, but also to test the feasibility of this technology and found that the what are the technology issues and how to improve. Higher Power of the highest difficulty of building, more problems, more evident. ”
demonstration power plant can provide 24 hours of operation, produces a current directly to the school, 380V low voltage line, full load plant in the vicinity to respond to the luxurious five-star standard - the normal functioning of Chinese workers international academic centers. “Power station demonstration by-product water is 50 degrees Celsius, is very suitable for hot water used in daily life. In the heat and electricity have been under-utilized plants to fuel cells will reach 90 percent energy efficiency. “Shi-Jun Liao description.
In the demonstration power plant, first converted to hydrogen gas, hydrogen fuel cell generates electricity and hot water generators.
According to reports from South China University of Technology design and development of hydrogen technology, natural gas, the hydrogen production efficiency is greater than 2.0 or 1 cubic meter of gas to generate more two cubic meters of hydrogen gas for hydrogen production facilities to a similar degree of internal efficiency by 20% 30%. That electricity generated by burning natural gas directly at least 30% higher, emissions are reduced by 60% year on year. power generation fuel cell with high efficiency and low emissions that accentuates the advantage.
The use of new technologies to reduce the cost of fuel cells
R & D of fuel cell technology for decades, has been promoting large scale, there is less stability, durability and so on, ultimately, the high cost of marketing is the bottleneck.
Shi-Jun Liao said that foreigners proton exchange membrane fuel prices at about 70,000 yuan per kilowatt to install a car battery system of 50 kilowatts, solar cells of 3.5 million yuan. Thus, while in technological research, how to effectively reduce the cost of fuel cells has been a group of major research topic.
Due to the use of new technologies developed by the present South China University of cost of fuel cells have decreased from 6000 to 7000 yuan per kilowatt, only the international market price for 1 / 10.
“Compared to conventional technologies for electricity production, the cost is high, but other than new energy such as solar energy, but much cheaper.” Shi-Jun Liao calculations, the calculation of 6,000 yuan per kilowatt, fuel cell vehicle costs are still not cheap, but compare the hydrogen cheaper than gasoline!
To promote the development and use of fuel cell, our country has introduced subsidies, buy a car fuel cell, direct subsidies to 300,000 yuan. In addition, the mass production of fuel cell costs are significant decline in the space. At the same time, many governments have said that once the large-scale commercialization of fuel cell development of hydrogen stations in the building will not be a problem, the fuel cell in the civilian population to house just around the corner.
It is understood that the demonstration plant is complete, many experts at home and abroad have visited the station after the sigh. British Adviser to the Government’s Energy, experts from fuel cells, Imperial University Professor Nigel Brandon attended a demonstration of the power station, said: “It’s a miracle! A panel discussion with the University so little funding to complete an arduous task to develop such a good system of high power fuel cell is simply incredible! ”
According to reports in recent years, in addition to completing the construction of power plants, South China University of proton exchange membrane cell technology research base has also made a series of significant achievements, including preparation of highly dispersed and active catalyst technology, the light directly on Preparation of membrane-electrode membrane technology, efficient technologies platinum catalyst at very low loading of platinum electrode membrane technology. Group discussion of core technologies for patents for fuel cells 8, 4 allowed to request an international patent. sony-vgp-bps9.htm”>vgp-bps9
Regarding the plan for the next step, Liao Shi-June, said: “We’ll use the Guangzhou Institute of modern industrial technology to carry out the platform of the industrialization of fuel cells in working on a series of fuel cell emergency power, base stations, power, communications, household cogeneration system and other products. We hope to further reduce the cost of fuel cells, and promote the development of fuel cell technology in the province of Guangdong and the commercialization process. “
