In the past one or two decades, the United States has paid special attention to the research and development of fuel cells, while Japan has vigorously carried out technological development based on the introduction of American technology. The reason why fuel cells have attracted the attention of some developed countries is mainly because it has the following advantages:
1) High efficiency. Because the chemical energy of the fuel is directly converted into electrical energy without thermal energy conversion in the middle, the conversion efficiency is not limited by the thermodynamic Carnot cycle; because there is no conversion of mechanical energy, mechanical transmission losses can be avoided, and the conversion efficiency does not depend on the size of the power generation. And change, so the fuel cell has higher conversion efficiency;
2) Low noise and low pollution. In the process of converting chemical energy into electrical energy, the fuel cell has no mechanical moving parts, but the control system has some small moving parts, so it is low-noise. In addition, fuel cells are low-pollution energy sources. Taking phosphoric acid fuel cells as an example, the sulfur oxides and nitrogen compounds they emit are two orders of magnitude lower than the U.S. regulations;
3) Strong adaptability. Fuel cells can use various hydrogen-containing fuels, such as methane, methanol, ethanol, biogas, petroleum gas, natural gas and synthetic gas, etc. The oxidant is inexhaustible air. Fuel cells can be made into standard components with a certain power (such as 40 kilowatts), assembled into different powers and types according to the user's needs, and installed in the most convenient place for the user. If necessary, it can also be installed into a large power station and used in connection with the conventional power supply system, which will help regulate the power load;
4) Short construction period and easy maintenance. After the industrial production of fuel cells is established, various standard components of power generation devices can be continuously produced in factories. It is easy to transport and can be assembled on-site at the power station. Some people estimate that the maintenance required for a 40-kilowatt phosphoric acid fuel cell is only 25% of that of a diesel generator of the same power.
Because fuel cells have so many advantages, both the United States and Japan attach great importance to its development.
