Overview
Graphite composite bipolar plates are used in electrochemical cells — fuel cells and flow batteries in the hydrogen sector in particular. The plate conducts current, distributes reactant gas, separates adjacent cells and supports the stack; it accounts for a significant share of stack volume and cost.
Why Graphite Composite
- Conductivity: graphite filler builds conductive paths in-plane and through-thickness.
- Corrosion resistance: stable in the humid acidic environment of a fuel cell, where metal plates need coating protection.
- Formability: compression moulding allows thin walls and integrated flow fields at production volume.
- Gas tightness: the resin matrix separates hydrogen from oxygen.
Applications
PEM fuel cell stacks, flow battery stacks, and separation and conduction structures in electrochemical storage.
Background
Gengchi New Energy was founded in 2020 as the company’s entry into hydrogen and energy storage; graphite composite bipolar plates are developed and manufactured there. In October 2026 a Xiangjiang New Area delegation on hydrogen industry development inspected its automated bipolar-plate line.
Delivery
Diameter, strength, spool length and packaging are confirmed against the machine and duty; MOQ, sampling and production lead time on inquiry.
