Product Description

Product Description

Graphite bipolar plates are key components in proton exchange membrane fuel cells (PEMFCs) and other types of fuel cells. They serve as the conductive interface between adjacent cells and play multiple critical roles in ensuring efficient operation of the stack.

Material Advantages 
1.High Electrical Conductivity 
2.Excellent Corrosion Resistance 
3.Lightweight and Thermally Stable 
4.Machinability for Flow Field Design 

Main Functions

Electron Conduction | 
Transfers electrons from anode to cathode through an external circuit.

Gas Distribution | 
Evenly distributes hydrogen and oxygen gases to the catalyst layers.

Heat Management | 
Helps manage heat within the fuel cell stack.

Sealing and Mechanical Support |
Ensures separation of gases and provides mechanical stability.

Applications

Proton Exchange Membrane Fuel Cells (PEMFCs)
Commonly used in automotive fuel cells, backup power systems, and portable power devices.

Phosphoric Acid Fuel Cells (PAFCs) 
Typically in stationary power generation.

Electrolyzers
For hydrogen production in renewable energy systems.

Flow Batteries 
Acts as both a current collector and structural component.
