Conductive Graphite Bipolar Plate

Conductive Graphite Bipolar Plate takes high-purity graphite (carbon content ≥99.95%) as the base material, **and is integrated** with advanced forming technologies (such as compression molding, isostatic pressing, or extrusion) and surface modification processes (e.g., carbon coating, metal plating). Its core value lies in solving three key pain points of traditional bipolar plates(metal, resin-based):

• Eliminating "corrosion-induced conductivity decay" in acidic fuel cell environments;
• Reducing "energy loss caused by high contact resistance";
• Balancing "structural strength" and "lightweight demand" for vehicle-mounted/portable scenarios.

Ultra-High Conductivity & Thermal Conductivity
Effectively reduces internal resistance of fuel cell stacks, with volume resistivity ≤20 μΩ·m (RT) and thermal conductivity 150–300 W/m·K, ensuring uniform heat distribution and avoiding local overheating (a top concern in 68% of automotive fuel cell projects).

Excellent Corrosion Resistance
Resists corrosion from acidic electrolytes (e.g., proton exchange membranes) and high-humidity environments; no obvious performance decay after 5,000+ hours of continuous operation in 0.5mol/L H₂SO₄ solution (meets the durability requirements of 90% stationary and mobile fuel cell systems).

Precision Structure & Sealing
Integrally formed flow channels (width 0.5–2mm, depth 0.3–1.5mm) with dimensional tolerance ±0.05mm, ensuring uniform distribution of hydrogen/air and preventing fluid cross-leakage (critical for stack efficiency, as per big data on stack failure causes).

Lightweight & High Mechanical Strength
Conductive Graphite Bipolar Plate has a density of 1.7–1.9 g/cm³ (1/3 the density of metal bipolar plates), reducing the stack weight by 20–30%. It also has a flexural strength of ≥40 MPa and a compressive strength of ≥120 MPa, which allows it to withstand stack clamping force and adapt to vehicle vibration and impact

Long-Term Stability & Low Maintenance
No need for anti-corrosion coatings (avoiding coating peeling risks), service life ≥10,000 hours (meets the 8-year/160,000km warranty requirement for hydrogen fuel cell vehicles).

Hydrogen Fuel Cell Vehicles
Core component of PEMFC (Proton Exchange Membrane Fuel Cell) stacks for passenger cars, commercial vehicles, and trucks; responsible for conducting current, distributing reaction gases (H₂/air), and removing water/heat.

Distributed Energy Systems
Used in household/industrial fuel cell power generation (1–100 kW), providing stable power output with low noise and zero emissions (popular in areas with renewable energy storage needs).

Portable Power Supplies
Integrated into lightweight fuel cell power packs for outdoor operations (military, field exploration) and emergency rescue, replacing traditional lithium batteries with longer endurance.

Rail Transit & Maritime
Applied to hydrogen-powered trains and ships, adapting to harsh environments (high humidity, salt spray) with excellent corrosion resistance.

Energy Storage Systems
Matched with solar/wind energy storage systems, serving as a key part of "renewable energy + fuel cell" hybrid energy storage, improving grid stability.
