fieltro de fibra de titanio
Hydrogen transportation is an important part of hydrogen energy utilization. Generally speaking, there will be a certain distance between hydrogen production plants and users, which requires hydrogen transportation. Based on the different state of hydrogen during transportation, it can be divided into gas hydrogen transportation, liquid hydrogen transportation and solid hydrogen transportation. The first two...

At present, there are four main paths for global hydrogen storage: High-pressure gaseous hydrogen storage technology, low-temperature liquid hydrogen storage technology, solid-state hydrogen storage technology and organic liquid hydrogen storage technology The mainstream of development in China’s hydrogen storage industry is high-pressure gaseous hydrogen storage, and most hydrogen refueling stations use high-pressure hydrogen storage. High-pressure...

Titanium Felt LGDL: titanium felt liquid gas diffusion layerLGDL: liquid gas diffusion layerCL: catalyst layer To reduce the interfacial resistivity between the LGDL and CL. There are two different surface treatments: sputter coating and thermal nitriding. Sputter Coating Firstly, as shown in Figure 1, sputter coating is a physical vapor deposition (PVD) method of thin...

En la actualidad, en el PEMEC, la capa de difusión de líquido/gas de fieltro de titanio (LGDL) se encuentra entre la capa de catalizador (CL) y la capa de recogida de corriente con campo de flujo. En cuanto al propósito de la LGDL de fieltro de titanio, es transportar electrones, calor y reactivos/productos hacia y desde la CL con mínimas pérdidas de corriente, térmicas y fluídicas....
