What is the minimum bending strength and conductivity guaranteed for the Atomfair composite graphite bipolar plate assembly?
The Atomfair composite graphite bipolar plate assembly (model AF-CG-BP462) guarantees a bending strength of at least 50 MPa and a conductivity of at least 300 S/cm, as specified in the technical specifications. These values are critical for structural integrity and electrical performance in fuel cell stacks.
What dimensional tolerances and flatness must be maintained for integrating this bipolar plate assembly into a fuel cell stack?
The assembly has dimensions of 462 x 122 mm with a thickness range of 1.2-1.4 mm, precision of +/-0.02 mm, and flatness of <=0.03 mm. These tolerances ensure proper alignment, uniform contact pressure, and effective sealing within the stack.
What permeability level is required to ensure gas tightness in this composite graphite bipolar plate assembly?
The assembly must achieve a permeability of <=2 x 10^-8 cm3/(cm2.s) to meet gas tightness requirements. This is controlled through the impregnation, bonding, and sealing processes applied during manufacturing.
Composite graphite bipolar plate assembly with 462×122 mm dimensions, 1.2-1.4 mm thickness, bending strength >=50 MPa, conductivity >=300 S/cm, and contact resistance 3.5-4 mohm-cm, suitable for fuel cell applications requiring low permeability and high corrosion resistance.
Positive
- High strength and conductivity: Bending strength >=50 MPa and conductivity >=300 S/cm enable structural integrity and efficient electron transport in fuel cell stacks.
- Low contact resistance and controlled permeability: Contact resistance of 3.5-4 mohm-cm and permeability <=2e-8 cm3/(cm2.s) minimize power losses and gas crossover, critical for stack performance.
Trade-offs
- Tight dimensional tolerances: Thickness range 1.2-1.4 mm with +/-0.02 mm precision and flatness <=0.03 mm require careful handling and precise integration to avoid compromising seal integrity.
- Permeability verification needed: Permeability <=2e-8 cm3/(cm2.s) must be confirmed against application-specific gas-tightness requirements, as even low permeability may affect long-term durability in certain operating conditions.
