At present, countries are carrying out energy system reforms and attach great importance to the research and development, and application of new energy technologies. The new energy technology development is to deal with the increasingly serious environmental degradation and energy shortage problems.
Ballard Power Systems of Canada first applied fuel cell technology to buses in 1993. In 2006, the United States strengthened its support for the application of fuel cell technology and launched the national fuel cell bus program. And major automobile companies led by General Motors successively carried out research and development of fuel cell vehicle technology. Japan Toyota released the first-generation Mirai fuel cell vehicle as early as 2014, which can achieve 502 kilometers. China has also listed fuel cell technology as one of the key research directions for new energy technologies.
A fuel cell is an energy conversion device. The reactants of the cathode and anode undergo an electrochemical reaction under the action of a catalyst. The chemical energy in the fuel is converted into electrical power and exported. The chemical energy in the fuel is converted into electrical energy and exported. During process of energy conversion, it will not be limited by the Carnot cycle, and it can have high energy conversion efficiency.
Now at electric vehicle and energy storage area, lithium battery is a popular choice which has advanced technology. Greenbatt wall mounted battery has 8000 cycles and matched many well-know inverters such as GOODWE, Deye, Sunsynk, Sofar, Growatt and Victron.
