Analysis of the characteristics of hydrogen fuel cells

Source: 2020 - 03 - 28 15:06 hits: hydrogen fuel cell characteristics ( 1) Good environmental compatibility of hydrogen fuel cells with efficient clean energy, the discharge of water not only less, and very clean, so there is no water pollution problems. Like engine because the fuel cell does not need to convert heat into mechanical energy, but directly convert chemical energy into electrical energy and thermal energy, high energy conversion power, low noise. ( 2) Good operation with hydrogen fuel cell power generation does not require any messy devices, and cell stack can be modular. For instance, a 4. 5 mw power plant can be composed of 460 battery module, its power plants than coal-fired power plant covers an area of much smaller. Hydrogen fuel cell is suitable for the power supply of power generation equipment. Compared with other thermal power plants, hydropower and nuclear power plant, hydrogen fuel battery factories manufacturing cycle is short, simple expansion, according to actual need stage production. Coupled with the high quality of hydrogen fuel cells work, ability to cope with rapid load change, Such as peak load) Is very good, in a few seconds can transfer from low power to the rated power. ( 3) Effective output of the hydrogen fuel cell will be stored energy of fuel into electricity and heat, produced more than 40% of its electricity, and electricity only one-third of the turbine. ( 4) Activation of the structural characteristics of hydrogen fuel cell assembly is very bright, brief power size distribution, compared with the traditional engine, excellent performance due to hydrogen fuel cell module is enough not to increase investment in infrastructure, on the basis of the number of finished products through single battery can easily increase or decrease the output power and voltage adjustment, so also is very short, and complete control of power grid is relatively short. The characteristics of fuel cell to improve the stability of the system. ( 5) Hydrogen source of hydrogen is a kind of secondary energy, can be gained through a variety of methods, such as hydrogen production from coal, transformation of hydrogen production from natural gas, from water electrolysis hydrogen production, etc. As the fossil energy consumed, hydrogen will become the main fuel and energy in the world. Use the solar energy water electrolysis hydrogen, in the absence of carbon emissions in the process, hydrogen is the ultimate power. ( 6) From the point of the development of the current existing bottlenecks, hydrogen fuel cell has met certain bottlenecks, such as high cost of battery itself, the lack of a wide range of infrastructure.
