The 20th century is a period of high-speed development of the world economy. After experiencing the high-speed development of the industry revolution and industry, it also produced serious environmental issues. With the enhancement of people's environmental awareness, the 21st century is already the century of the environment. The common problem facing human beings is how high-efficiently use the Earth's increasingly limited resources, protecting the environment of humanity. The improvement of human living standards should be established on a good economic, resource and environmental balance.In 1970, the annual average annual growth rate of electricity in the world is 4%, and the electricity is different from other daily necessities. It is closely related to modern living standards. It has huge impact on people's lives. It has been shown that people's expected life and per capita The power has a significant correspondence. Adult cultural levels also have similar relationships with the amount of electricity occupied by per capita. Power and national economic development also have a close relationship. According to the International Energy Department, from 1991 to 2010, the world's new generation of power generation is 1431 GW, an average increase of 79.5GW per year, which is equivalent to an increase of 1528 m W power plants. The famous Indian Dhabol Power Plant and the Pakistan Haber River (HAB) hydropower station, and its own power generation capacity cannot reach 1500 mW.
While recognizing electricity, it should also be noted that the power industry is also a huge pollution source. CO emissions in the electric power industry is 25%, NO 2 and SO two each account for total 40% of emissions
In the past few years, the power industry is undergoing structural changes, centrally powering is being challenged by decentralized power. The current power industry is a monopolistic industry. Due to scale, the scale of power plant / station is large, and it is far from the user, and power is delivered to the user through high voltage lines and substations. Dispersion power station, including steam turbine power station, internal combustion engine power station, solar power station, wind power station, fuel cell power station, etc. It is very close to the user to reduce costs and improve services.
The fuel cell is used in recent years for a decentralized power supply system. The advantage of the fuel cell power station is that high efficiency, low pollution, low noise, easy to achieve automation, and strong compatibility with other types of power stations, is excellent and reliable energy. The PAFC power system has already entered the stage of commercialization. In general, the current power supply cost of fuel cells is higher. The cost of the fuel cell power supply system mainly includes, battery stack, fuel processing apparatus, power conversion and control device. These costs can be reduced by improved technology.
