Application status of hydrogen fuel cells

1. Application in decentralized power stations. In some large power stations, whether thermal, hydro or nuclear, electricity is sent to the grid and then transmitted to customers. However, different users have different loads, so it will cause voltage instability or power outage. Moreover, because of the traditional thermal power generation combustion, needs a large amount of fossil fuels, and will also emit a large number of toxic gases into the air. But for hydrogen fuel cell application, energy conversion efficiency will be higher, and has less noise, no pollution, flexible use, so it has a wide range of applications.

2. Application in battery cars. At present, a research hotspot of fuel cells is the application of hydrogen fuel cells in automobiles. Many world famous automobile enterprises have launched hydrogen fuel powered vehicles. Through the application of fuel cells, air pollution is continuously reduced, and the dependence of modern society on oil is continuously reduced. China's fuel cell vehicle technology research and development has been a great development, has mastered the relevant core technology. It has also established a fuel cell vehicle powertrain technology platform, as well as a set of research and development system. Through a long time of research abroad, fuel cell vehicle products in environmental adaptation and reliability have also made a great breakthrough, and continue to deepen, fuel cell vehicle has advanced to the technology and market demonstration stage.

3. Military applications. The UK's Defence Assessment and Research Agency has identified solid oxide fuel cells as the most suitable option for future naval vessels, in line with the power requirements of surface ships. The Netherlands has also carried out related research on fuel cells. Through the feasibility demonstration and related design and experiments of fuel cells, it is concluded that the changing conditions will not have obvious impact on the performance of fuel cells. Therefore, the development prospect of fuel cells in warship application is broad and has high safety.

4. Application in mobile power supply. With the development and improvement of society, science and technology have made great progress. At present, electronic devices such as mobile phones and computers are applied all over the world, and these devices have more and more functions, so it is necessary to increase the energy density of batteries and increase the use time of these devices. However, the current lithium-ion batteries on the market have been unable to meet people's increasing demand. But some companies in the world have developed PEMFC as a mobile phone battery scheme, mobile phone standby time can reach 1000H. Hydrogen fuel cells could also be used in some portable chargers.
