Graphite for Fuel Cells

Fuel cells generate electricity through an electrochemical reaction between hydrogen-rich fuel and oxygen, and are used in applications ranging from stationary power systems to vehicles like buses and submarines. A critical component of these systems is the bipolar plate, which distributes gases, conducts electricity, manages heat, and prevents leaks. Graphite is widely used for these plates due to its excellent electrical and thermal conductivity. To ensure optimal performance and durability, the graphite must be of high purity and quality, enabling efficient energy transfer and long operational life.

How can we help address your challenges?

Issue

Stainless steel, while mechanically strong, lacks the electrical and thermal conductivity needed for optimal fuel cell performance.

Solution

Superior Graphite’s FormulaBT™ graphite powders offer high through-plane electrical and in-plane thermal conductivity, making them ideal for high-efficiency fuel cell applications, especially in stationary systems.

Issue

Bipolar plates made with low-purity graphite are prone to corrosion, leading to reduced operational life and reliability.

Solution

Using Superior Graphite’s Electro-Thermal Treatment/Purification Technology, high-purity graphite is produced to significantly enhance corrosion resistance and extend the service life of bipolar plates.

Issue

Graphite-polymer composites often struggle to balance mechanical strength with ease of processing during plate manufacturing.

Solution

FormulaBT™ powders are engineered to deliver good mechanical properties and compatibility with polymer binders, enabling easier processing and robust plate formation.

Issue

Inconsistent material quality and supply interruptions can hinder large-scale fuel cell production and deployment.

Solution

Superior Graphite ensures consistent quality and scalable supply of FormulaBT™ graphite powders, supporting reliable production and long-term project planning for OEMs and integrators.
