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

Titanium felt is a highly versatile material that has a wide range of applications in various industries. Including aerospace, chemical processing, and energy. This material created sintering titanium fibers together into a porous structure. resulting in a lightweight, high-strength material that exhibits unique mechanical and thermal properties. One of the most significant advantages of titanium

Precious metal catalysts Noble metal platinum-based catalysts Noble metal platinum-based catalysts (PGMs) are the best performing HER catalysts available. It has low overpotential, high exchange current density and remarkable reaction stability. It can effectively reduce the hydrolysis energy barrier and increase the reaction rate. The disadvantage is that resources are scarce and expensive, which limits
