Good Structure High Strength Nanometer Pure Nickel Foam for Motor Muffler

Porous High Strength Nickel Metal Foam Uesd for SOFC Electrode Relay Fedders

Introducction and Application Clasification:

Nickel Foam Industrial Application- high purity nickel foam produced in a wide porosity range (~70% to 98%) and based on the structure of reticulated polymer foam. nickel foam are suitable porous three-dimensional anodes for the oxidation of organic substrates. Metal foams are metal cellular structures containing a large volume fraction of gas-filled pores. They are a relatively new class of materials, which has been developed for applications in lightweight structures. They offer low densities and, due to their high stiffness to weight ratio, they show potential for energy absorption and mechanical damping. There are two types of metal foams, open cell metal foam, where the pores do interconnect, and closed cell metal foams with sealed pores. Nickel foam possesses unique features such as exceptional uniformity, light weight, high porosity, intrinsic strength, corrosion resistance, and good electrical and thermal conductivity.

1, battery electrode material

Foam nickel is mainly used for battery electrode materials, especially for NiMH batteries. Such rechargeable batteries are widely used in laptop computers, mobile phones, electric scooters, electric bicycles, and hybrid vehicles.

2, fuel cell

Molten carbonate fuel cells typically operate at temperatures between 550 and 700 ° C, and foamed nickel can be an electrocatalyst for molten carbonate fuel cells. Nickel foam can be used for bipolar plate modifying materials for proton exchange membrane production cells (PEMFC), electrode relay feeders for solid oxide fuel cells (SOFC), and electrode materials for electrolysis (as in water electrolytic environments). The increased surface area can also be used to generate hydrogen and syngas for fuel cells.

3. Catalyst materials

The unique open-cell structure, low-pressure input hole, inherent tensile strength and thermal shock resistance make foamed nickel possible as a catalyst carrier for automotive catalyst converters, catalytic combustion, and diesel black smoke purifiers. When the engine is cold-started, carbon monoxide and hydrocarbons are converted. Due to the heat transfer properties, the foamed nickel catalyst carrier may be superior to the ceramic catalyst carrier. In this sense, the foamed nickel may be compared with the high temperature resistant steel catalyst carrier or higher than the high temperature resistance. The steel catalyst carrier is superior. Other applications of the foamed nickel catalyst may include a Fischer-Tropsch reaction, a gas modification, a hydrogenation reaction of a fine chemical, a foam catalyst support.

4, other applications

Nickel foam can be used as a filter material to treat magnetic flux conductors of magnetic particles in a fluid. Other applications include application to hydrogen storage media, heat exchange media.

Gas layer material for various industrial and civil infrared burners

Fluidized plate porous material made of foam metal material

The control of fluid distribution state, the transfer of powder materials and the fluidized bed operation have been widely used in industrial processes. Especially, fluidized bed technology is an important means for mass transfer, heat transfer, mixing and chemical reaction in chemical processes. . Among them, the control of the gas distribution state requires the use of a gas permeable orifice material. The foam metal porous fluidized plate is made by cutting using the world's leading new porous metal material. It has a unique three-dimensional uniform through-hole structure, uniform pores, porosity of 95%, and through-hole ratio of over 98%. It can be used in petrochemical, metallurgical machinery, energy and environmental protection, textile and electric power, aerospace, pharmaceutical and other industries with rectification, powder conveying, gas diffusion, drying, soaking, environmental protection and other functional requirements.
