MEA (Membrane Electrode Assembly), also known as membrane electrode, is the heart of the fuel cell. The CCM (catalyst coated membrane) and the cathode/anode diffusion layer are the main site of the electrochemical reaction, involving the occurrence of the reaction and the transfer and emission of the products. Platinum loading Amount of precious metal platinum

Recently, the world’s first offshore pilot test of in-situ direct electrolysis of hydrogen production technology for offshore wind power without desalination of seawater confirmed by a group of experts from the Chinese Academy of Engineering. After an on-site inspection at Xinghua Bay offshore wind farm in Fujian, China. The offshore pilot test The offshore pilot

Germany’s ruling cabinet has approved plans to create a hydrogen core network to distribute hydrogen as an energy carrier nationwide. And the proposed bill is part of Germany’s strategy to achieve carbon neutrality in the coming years. Green hydrogen is an integral part of these plans. Robert Habeck, German Minister for Economic Affairs and Climate

At present, there are many methods to produce hydrogen energy. It can be roughly divided into the following categories according to the different ways and principles of raw material conversion: solar thermal chemical hydrogen production, fossil energy hydrogen production, biomass hydrogen production and electrolysis of water hydrogen production, etc. (1) Solar thermal chemical hydrogen production

As we all know, the important material basis for all aspects of national development is energy. The development of energy is directly related to the level of modernization of a country. There are three main types of energy that people now use: one is energy from celestial bodies other than the Earth, such as the

Fiber size The pore size of nickel fiber mat has a great influence on the filling performance of the active material. If the pore size is too small, the active material is not easy to fill. And then the active material only concentrated on the surface of the electrode, but not filled inside. If the

Abstract A Ni metal fiber felt is recommended for use as an anode substrate in the metal hydride-nickel(MH-Ni) battery instead of foamed nickel in the development of a high capacity, high current battery. The processing of the Ni fiber felt is describe. The influence of fiber diameter and area density on the pore size, porosity.

The present invention belongs to the field of preparing metal porous materials. It provides a new process for preparing hollow nickel fiber mats with high porosity. A new method of preparing hollow nickel fiber mat Metal porous materials are usually made of metal powder by pressing (rolling) and sintering. However, due to the few contact
