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...Read More

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...Read More

Membrane electrode assembly, also known as membrane electrode, is the key core component of fuel cell power generation, which is composed of gas diffusion layer, catalyst layer and proton exchange membrane. membrane electrode Principle Hydrogen reaches the anode through the gas flow field on the anode plate, reaches the anode catalyst layer through the diffusion...Read More

In the proton exchange membrane fuel cell, the main function of the gas diffusion layer is to support the catalyst, and to provide a channel for the gas involved in the reaction and the water produced, and it is one of the key components of the membrane electrode. The gas diffusion layer is mainly used...Read More

Titanium felt LGDL Performance comparison 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. Performance comparison curves between there different thickness ti felt LGDLs (square: 350 um thickness; circle: 500 um thickness; triangle:...Read More

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...Read More

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...Read More

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....Read More
