Eliminate traditional power generation methods Eliminate traditional power generation methods – Cheersonic In-depth analysis: With the advent of fuel cells, will traditional power generation methods be eliminated? The basic working principle of  fuel cells  may not be difficult to explain. However, manufacturing cheap, efficient, and reliable fuel cells is a very complicated matter. In order to improve efficiency, scientists have designed many different types and sizes of fuel cells, each of which has different technical details. Many of the choices faced by fuel cell developers are limited by the choice of electrolyte. For example, the design of the electrode and the material used to make the electrode depend on the electrolyte. Today, the main electrolyte types are alkali, molten carbonate, phosphoric acid, proton exchange membrane (PEM) and solid oxide. The first three are liquid electrolytes; the last two are solids. The type of fuel also depends on the electrolyte. Some b...

The heart of fuel cells-membrane electrodes Ordered membrane electrode is undoubtedly the main direction of the next generation of membrane electrode preparation technology. While reducing the platinum group element load, the following 5 aspects need to be further considered: 1) Ordered membrane electrode is very sensitive to impurities; 2 ) Broaden the operating range of membrane electrodes through material optimization, characterization, and modeling; 3) Introduce fast proton conductor nanostructures in the catalytic layer; 4) Low-cost mass production process development; 5) In-depth research on membrane electrode proton exchange membranes, electricity The interaction and synergy between the catalyst and the gas diffusion layer.

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...
