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. Various applications are discussed below.
nickel foam industrial application
Ni foam has been predominantly used in battery electrodes, especially for NiMH batteries. Such rechargeable batteries have found applications extensively for portable computers, cellular phones, battery-powered scooters, bicycles and hybrid electric vehicles effective surface area of the electrode active materials could thus be increased to enhance the high power capability. The uniform structure has now been extended to a wide range of specifications including 0.2 – 2.6 g/cm3 densities and 450 to 3200 µm pore sizes foams. Nickel foam is mainly used for battery electrode material is particularly useful for NiMH batteries, the rechargeable battery is widely used in the portable computer, mobile phone, electric scooter, electric bicycle, hybrid cars.
Ni is active in hydrogen dissociation at elevated temperatures. This makes Ni foam a potential material as an electro catalyst in molten carbonate fuel cells (MCFC), which normally operate at 550-700ºC. Chemical environment of MCFC fuel cells is such that nickel can be used for both electrodes. Nickel Foam Industrial Application with wide range of density specifications provides a good structure for these applications as it offers high porosity, good gas distribution characteristics and thermal stability. Ni foam may find applications as bipolar plate enhancement material for proton exchange membrane fuel cells (PEMFC), electrode interconnectors for solid oxide fuel cells (SOFC), and electrode materials in electrolysis such as hydrogen electrolyzes. It may also be enhanced in surface area for potential use in steam reforming reactions to supply hydrogen or syngas for fuel cells.
Molten carbonate fuel cell usually work temperature between 550-700 DEG C, Nickel foam can become the electro catalyst for molten carbonate fuel cell. Nickel foam can be used for proton exchange membrane (PEMFC) of the battery producing bipolar plate material modification, solid oxide fuel cell (SOFC) of the relay feeder, electrolysis electrode materials (such as in water electrolyses environment). To increase the surface area but also can be used for the generation of fuel cell with hydrogen and synthesis gas.
Due to the unique open cell structure, low pressure drop, intrinsic strength and resistance to thermal shock, nickel foam industrial application has potential as a catalyst support for automotive catalytic converters and catalytic combustion, and for catalytic filters for diesel engine particulates. Its high thermal conductivity may be superior to ceramic monolith supported catalysts in low light-off conversion of carbon monoxide and hydrocarbons during engine cold start. In this sense, Ni foam may be comparable or superior to high temperature steels as catalyst supports. Other catalyst applications of nickel foam may include foam supported catalysts for Fisher-Tropsch reaction, steam reforming and hydrogenation of fine chemicals.
Nickel Foam Industrial Application in classical filter-press type electrochemical cells. For this purpose the Electro SynCell, commercialized by Electrocell AB, has been used. The interest of using metallic foams linked to a classical plane plate is to improve the performance of the electrochemical cell by increasing the electrode surface area. Moreover, for some industrial applications it is possible to use the cell without a membrane. In the proposed configuration, the working electrodes consist of metallic foam linked to a plane plate and the auxiliary electrode is simply a plane plate. The imbalance between the surface areas of working and auxiliary electrodes allows operation with a single hydraulic circuit. This paper, focuses on the study of residence time distribution and pressure drop in order to compare the flow behavior with that in a classical configuration.
Owing to its uniform 3-D structure with custom porosity, nickel foam may find applications as a filter material. Its magnetic properties may make it suitable as a magnetic flux conductor for handling magnetic particles in a fluid. Other applications may include hydrogen storage medium, heat exchanger medium, and even in arts owing to its unique shaping capabilities, wide porosity range and environmental stability.
Nickel Foam Industrial can be used as filter material, processing of magnetic particles in the fluid magnetic conductor. Other applications include applications in hydrogen storage media, heat exchange medium.
Nickel Foam Industrial operation at present development situation is good, the enterprise is gradually to the industrialization, large-scale development. Nickel foam is a kind of excellent sound absorption material, sound absorption coefficient is higher in the high frequency; through the design of sound absorption structures can improve the sound absorption property in low frequency.
