Fuel Cell

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...

  Fuel Cell Structure The main components of a fuel cell are: electrodes, electrolyte membrane and current collectors. 1. Electrode The fuel cell electrode is an electrochemical reaction site where the fuel undergoes oxidation reaction and the oxidant undergoes reduction reaction. The key to its performance lies in the performance of the catalyst, the electrode material and the electrode manufacturing process. The electrode can be divided into two parts. One is the anode and the other is the cathode. The thickness is generally 200-500mm. The structure is different from the flat electrode of the ordinary battery. The fuel cell electrode is a porous structure, so it is designed to be porous. The main reason for the structure is that most of the fuel and oxidant used in the fuel cell are gases, and the solubility of the gas in the electrolyte is not high. In order to increase the actual working current density of the fuel cell and reduce the polarization, a porous structure has been d...
