Product Description

GDL (Gas Diffusion Layer)

The gas diffusion layer (GDL) is one of the key components in fuel cells (such as proton exchange membrane fuel cells PEMFC, direct methanol fuel cells DMFC, etc.). It is located between the bipolar plate and the catalyst layer. Its main functions are to evenly distribute the reaction gas, conduct electrons, discharge the generated water, and provide mechanical support.

The gas diffusion layer performance directly affects the efficiency, stability and life of the battery. Future development directions focus on material lightweighting, water and gas management optimization and cost reduction.

Frequently Asked Questions

What is the primary function of the Gas Diffusion Layer (GDL)?

The GDL evenly distributes reaction gases, conducts electrons, manages water discharge, and provides mechanical support between the bipolar plate and catalyst layer.

What is the typical thickness and porosity of your GDL?

Our GDL features a thickness ranging from 100 to 400 μm with a high porosity of 70% to 80%.

How do you ensure the quality of the products?

We always provide a pre-production sample before mass production and conduct a final inspection before every shipment.

What is the electrical conductivity of this material?

The electrical conductivity is greater than 100 S/cm, ensuring efficient electron transport.

Is the GDL hydrophobic?

Yes, with a PTFE coating, it achieves a contact angle of over 120°, providing excellent hydrophobicity for water management.

What types of fuel cells are compatible with this GDL?

It is primarily designed for Proton Exchange Membrane Fuel Cells (PEMFC) and Direct Methanol Fuel Cells (DMFC).
