Pure sintered porous nickel plate is a material that has been manufactured using a sintering process, which involves compacting and forming nickel powder into a solid piece through the application of heat and pressure without melting it completely. During sintering, the nickel particles bond together, creating a porous structure with interconnected voids or pores throughout the material.

Sintered porous nickel plates are versatile materials used as Gas Diffusion Layers (GDL) in electrolyzers, crucial components in the production of hydrogen through water electrolysis. These plates play a pivotal role in facilitating the efficient transport of gases within the electrolyzer, enabling the electrochemical reactions that generate hydrogen and oxygen.

applications

1. Electrode Support: Porous nickel plates are commonly used as electrode supports in fuel cells. They provide a stable structure for the catalyst layer, typically made of platinum or other materials, where the electrochemical reactions take place.

2. Gas Diffusion: The porous structure of nickel plates allows for efficient gas diffusion within the fuel cell. In hydrogen fuel cells, for example, hydrogen gas needs to reach the catalyst layer where it reacts with oxygen to produce electricity. The porous nickel plate facilitates the diffusion of hydrogen gas to the catalyst sites.

3. Electrical Conductivity: Nickel is known for its high electrical conductivity, which is essential for maintaining electrical connectivity within the fuel cell system. The porous nickel plate helps in distributing the electrical current generated during the fuel cell reaction.

4. Water Management: In proton exchange membrane fuel cells (PEMFCs), water management is critical for efficient operation. The porous nickel plate can help in the removal of excess water produced during the electrochemical reactions, preventing flooding of the cell.

5. Durability and Corrosion Resistance: Pure nickel plates are durable and corrosion-resistant, making them suitable for harsh operating conditions in fuel cells. They can withstand the acidic environment of PEMFCs and the high temperatures involved in solid oxide fuel cells (SOFCs).

6. Stack Assembly: Multiple layers of porous nickel plates, along with other components like membrane electrolytes and gas diffusion layers, are assembled to form the fuel cell stack. The porous nickel plates provide structural support and facilitate efficient gas and electron transport within the stack.
