What are the advantages of customized PEM fuel cell stack
Release time:
2022-09-14
1. The customized PEM fuel cell stack has high power generation efficiency
A fuel cell is a power generation device that directly converts the chemical energy of fuel into electrical energy, so it is not limited by the Carnot cycle. In theory, the power generation efficiency of a fuel cell can reach 85%-90%. Under the premise, the total utilization rate of fuel can reach more than 80%.
2. The customized PEM fuel cell stack has less environmental pollution
The discharge of the fuel cell is water, which has relatively little pollution to the environment. Moreover, because the fuel cell is a chemical energy reaction, the carbon dioxide emission is reduced by more than 40% compared with the heat engine process, and the pollution to the atmosphere is relatively small. Most importantly, the structure of the fuel cell is very simple, so there are few moving parts, the noise generated during operation is very low, and the impact on human life is also small.
3. High specific energy
The specific energy of customized PEM fuel cell stack is very high, the specific energy of liquid hydrogen fuel cell is 800 times that of nickel-cadmium battery, the specific energy of direct methanol fuel cell is more than 10 times higher than that of lithium-ion battery, and the energy conversion ratio is large.
4. Wide range of fuels
The customized PEM fuel cell stack can use a wide range of fuels, as long as substances containing hydrogen atoms can be used as fuels in theory, such as natural gas, biogas, alcohol, etc. can be used as fuels for fuel cells. The need for energy diversification.
