Proton exchange membrane electrolyzer (PEM) hydrogen production cost analysis Alkaline electrolyzer has low electrolytic efficiency, requires the use of strong caustic alkali, requires the removal of water and alkali from the hydrogen. That is difficult to start and change the load quickly, and cannot adjust the speed of hydrogen production quickly. So it is poorly...Read More

On March 10, the Australian and German governments jointly launched the HyGATE program, a hydrogen innovation and technology incubation program. It aims to promote cooperation between Australia and Germany to set up a hydrogen energy value chain between the two countries. Then they will find pilot, test and demonstration projects along the hydrogen supply chain....Read More

Efficient catalysts appear to be important for green hydrogen preparation, chemical industry, fertilizer production and other economic sectors. In addition to the use of transition metals, various other metallic or non-metallic elements have now become the focus of research. Green hydrogen is an important component in a climate-neutral energy system. It is produced by electrolytically...Read More

If you are interested in our new product 1200mm*1200mm ti fiber felt GDL ,please feel free to contact us any time: [email protected]Read More

The reason for the low efficiency of hydrogen transportation is that the density of hydrogen storage is too low. At present, various methods of hydrogen transmission are actually transporting stored hydrogen. If the hydrogen storage density increases, the efficiency of hydrogen delivery will naturally increase. Scientists now boldly imagine the co-transmission of hydrogen and electricity,...Read More

Solid hydrogen transportation, it is relatively simple to use hydrogen storage materials to store and transport hydrogen, that is, use hydrogen storage alloys to store hydrogen, and then transport containers containing hydrogen storage alloys. Solid hydrogen has the following advantages:(1) The volumetric hydrogen storage density is high; (2) The working conditions of the container are...Read More

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

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
