Hydrogen energy is widely known as next generation new energy. There are three main core materials for hydrogen fuel cells: catalysts, gas diffusion layers, and proton exchange membranes.
The gas diffusion layer not only functions as a supporting catalyst layer and a stable electrode structure in the electrode, but also has various functions of providing a gas passage, an electron passage, and a drainage passage for the electrode reaction. The use of high-performance gas diffusion layer materials is beneficial to improve the overall performance of the electrode.
Sintered porous metals are widely used in electrochemical devices such as water electrolysers, unitised regenerative fuel cells (URFCs) as gas diffusion layers (GDLs), and batteries. Edgetech industries LLC can provide high quality porous titanium materials as gas diffusion layers, which have the following functions and advantages.
-Uniform porous structure, good gas permeability;
-Low resistivity, strong electron conductivity;
-Structure Tight and flat surface, reduce contact resistance and improve electrical conductivity;
-Has certain mechanical strength, proper rigidity and flexibility, which is beneficial to the fabrication of electrodes, and provides stability of electrode structure under long-term operating conditions;
-Appropriate hydrophilicity / hydrophobic balance, to prevent excessive moisture blocking pores and lead to decreased gas permeability;
-Chemical stability and thermal stability;
-Low manufacturing cost, high performance / price ratio.
Information for fuel cells
Fuel cells directly convert the chemical energy in hydrogen to electricity, with pure water and heat as the only by-products. Hydrogen-powered fuel cells are not only pollution-free, but a two- to three-fold increase in the efficiency can be experienced when compared to traditional combustion technologies. Fuel cells can power almost any portable devices that normally use batteries. Fuel cells can also power transportation such as vehicles, trucks, buses, and marine vessels, as well as provide auxiliary power to traditional transportation technologies. Hydrogen can play a particularly important role in the future by replacing the imported petroleum we currently use in our cars and trucks.
