Fuel Cell Graphite Plate of CD Graphite Company
Professional manufacturer of graphite bipolar plates for fuel cells, industrialization pioneer.
Over the years, our company has produced millions of graphite flow channel pole plates and graphite pole plates.
The bipolar plates produced by CD Graphite Company greatly reduce the size and weight of fuel cell stacks. It has the following features:
1 High Conductivity：Graphite’s excellent conductivity allows it to conduct electrons efficiently, ensuring an even distribution of current within the battery and reducing internal resistance.
2 Thermal Stability：Resistant to high temperature, adaptable to heat accumulation during fuel cell operation.
3 Chemical Stability：Strong corrosion resistance, resistant to fuel cell acidic environments (e.g., proton conductive media in PEMFC) and oxidative reactions, long service life.
4 Gas Impermeability：Dense structure effectively blocks cross permeation of hydrogen (anode) and oxygen (cathode) for increased safety.
5 Lightweight (compared to metal bipolar plates)：Low density reduces the weight of the fuel cell stack for mobile applications (e.g. cars, drones).
