Graphite plates serve multiple purposes in various industries due to their unique properties. They are used as conductors, receiving energy from the electrodes. They guide the flow of hydrogen and oxygen through their respective ends of the stack, ensuring that the maximum amount of gases and moisture comes in contact with the membrane. In fuel cells, graphite is used as a conductive material for the bipolar plates. These plates must be pure and of high quality to improve electrical and thermal conductivity, as well as ensure long-life operation.

Applications of Graphite Plates

Graphite plates are versatile materials with numerous applications in various industries. They are commonly used for structural ribs, components of kilns, and copper, zinc, and aluminum extrusion machines. They play a crucial role in cable manufacturing, carbide, electrodes, and plastic injection molding parts. They serve as lubricating and sealing plates, and are most widely used in bipolar fuel cell construction.

Fuel Cells

Graphite plates are used in the manufacture of PEM (Proton exchange membrane) fuel cells. These fuel cells are being developed for transport applications as well as for stationary and portable fuel cell applications.

Electronics Industry

Graphite’s electrical conductivity makes it a key material for electrical products like electrodes, brushes, and carbon rod batteries.

Mechanical Systems

Graphite plates find applications in mechanical systems where self-lubrication and low friction properties are essential. They are used as bearing materials, seals, and wear-resistant components in machinery, pumps, and engines.

Products Made of Graphite Plates: 
There are numerous products made from graphite plates. Here are some examples:
Electrodes

 Electrodes are often made of graphite due to its high level of conductivity. Graphite requires only three of its outer energy electrons to bond, leaving the fourth free to act in a delocalized manner. These delocalized electrons enable graphite to exhibit a high level of conductivity, explaining why the material is frequently used for electrodes.

Nipples

Nipples are manufactured with 100% needle coke and are used in the assembly of graphite electrodes. They are designed to meet industry specifications and customer expectations.

 

Cathode Blocks:

Cathode blocks are used in the lining of aluminum electrolysis cells. They act as a conductor by receiving the energy from the electrodes.

 

Furnace Linings

Graphite furnace linings are used in high-temperature furnaces due to their thermal stability and resistance to corrosion. They are used in vacuum, inert-gas, and sintering furnaces.

 

Core Bricks

Core bricks made of graphite are used in the core of all of the UK’s Advanced Gas-Cooled Reactors (AGRs). They act as a moderator, helping to keep the nuclear reaction going, and perform an important safety function.

 

Degassing Systems

Graphite degassing systems are used for purifying and degassing molten metal in industries such as aluminum and aluminum alloys manufacturing, zinc and zinc alloys manufacturing, magnesium and copper manufacturing, and precious metals and their alloys manufacturing.

 

Electrographite Powder

Electrographite materials have been processed to extremely high temperature to transform carbon raw materials to graphite. This process provides increased thermal conductivity, decreased electrical resistivity, increased chemical resistance, increased oxidation resistance, and improved purity.

 

Disks

Graphite disks are used in various industries due to their thermal stability, low cost, and good thermal conductivity. They are used in applications such as sealing material and in the aerospace industry for crafting art or large-scale production projects.

 

Machined Spheres

Machined spheres made of graphite are used in various applications due to their high strength, durability, and precision. They are used in industries such as aerospace, electronics, and glass for crafting art or large-scale production projects.

 

Nozzles

Graphite nozzles are used in the aerospace industry due to their many advantageous properties. Graphite is very temperature resistant, low cost, and has good thermal conductivity.

​

Each of these products leverages the unique properties of graphite, such as its high thermal stability, electrical conductivity, and self-lubricating characteristics, to perform specific functions in various industries and the specific functions and applications of these products can vary based on the specific requirements of the industry or application they are used in.
