Fuel Cell Advantages A fuel cell is a device that directly converts the chemical energy of fuel into electrical energy. Theoretically speaking, as long as the fuel cell is continuously supplied with fuel, the fuel cell can generate electricity continuously. It has been hailed as the fourth generation of power generation technology after water power, thermal power, and nuclear power. High power generation efficiency. Fuel cell power generation is not restricted by the Carnot cycle. In theory, its power generation efficiency can reach 85% to 90%, but due to various polarization limitations during operation, the current energy conversion efficiency of fuel cells is about 40% to 60%. If combined heat and power are realized, the total fuel utilization rate can be as high as 80%. Environmental pollution is small. When the fuel cell uses hydrogen-rich gas such as natural gas as fuel, the carbon dioxide emissions are reduced by more than 40% compared with the heat engine process, which is very...
