PEMEC tests were performed with 20ml/min flow rate of liquid water at the anode side and 80 degrees temperature; the performance and impedance results shows in Figure about titanium felt, respectively. With the further research, among three different thickness titanium LGDLs in Figure. It shows that the PEMEC with a 350 micron thickness titanium LGDL
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. Firstly, as shown in Figure 1, sputter coating is a physical vapor deposition (PVD) method of thin film deposition
At present, hydrogen production mainly contains four processes and technologies: 1. Electrolysis of water; 2. Fossil fuels; 3. Industrial by-products; 4. Biomass. Electrolysis of water can directly obtain fuel hydrogen without CO, but its high cost is not conducive to the widespread promotion of this technology. Although the cost of the three types of production
Titanium fiber felt, a diffusion layer material, provides electrons between the catalyst layer and the bipolar plate or the current distributor on the anode side. Due to its three-dimensional network porous structure, high porosity, high corrosion resistance and other characteristics, titanium felt has become one of the best materials of diffusion layer in fuel cell
As the global resource shortage is becoming more and more serious. In terms of new energy, especially the process of producing hydrogen from electrolyzed water. Many customers demand metal fiber felts with a thickness of 200-240 microns and a porosity of 70%. Titanium felt is essential for Electrolysis hydrogen production equipment. Due to the high
A new material titanium felt with a diameter of micrometers. It is made of metal titanium fiber by laying and sintering at high temperature. Titanium fiber felt has a three-dimensional network porous structure. Porosity and hole diameter are adjustable. Finally, it will obtain the best electrolytic performance during the electrolysis process. In the process of
At the present time, in the PEMEC, titanium felt liquid/gas diffusion layer (LGDL) is located between the catalyst layer (CL) and current collecting layer with flow field. As for the purpose of the Titanium felt LGDL, is to transport electrons, heat, and reactants/products to and from the CL with minimal current, thermal, and fluidic losses.
