Engineers often choose between graphite bipolar plates and coated metal bipolar plates when designing fuel cell stacks. Metal plates are thin and strong, but their anti-corrosion coating may degrade over cycles and raise contact resistance. Graphite bipolar plates gain popularity for long-life stationary and heavy-duty fuel cell systems thanks to stable material properties.

Key Advantages

Stable surface conductivity: No oxide layer buildup, maintaining consistent stack efficiency over thousands of operating hours.

Superior chemical stability: Resists corrosion by fluoride ions and acidic condensate.

Lower raw material cost for medium & large batch stationary power projects.

Easy to machine complex flow channels for optimized water management.

Applications

Telecom backup power, data center uninterrupted power supply, hydrogen forklifts, off-grid power generation, industrial electrolysis devices. Jiecheng Graphite can recommend suitable graphite grades and sealing processes to reduce gas permeability for your stack test and mass production.
