Bipolar plate material name:

1. Molded carbon composite bipolar plate.
2. Resin-free 100% sintered carbon bipolar plates.

 

the difference:

Unlike other carbon manufacturers, we start production from toner powder, and we can design the formula of carbon to meet customers' needs.

 

Production Process:

1. Raw material processing.
2. Molded according to the drawings provided.
3. The carbon composite material is heat treated. Resin-free carbon is directly sintered at around 2200°C.
4. Cleaning, testing, packaging.

 

density:

Carbon composite bipolar plate: ≥1.70 g/cm3.
Resin-free 100% sintered carbon bipolar plates: ≥1.80 g/cm3.

 

Air leakage detection: no air leakage within 0.1Mpa

 

feature:

 

Carbon Composite Bipolar Plates:

1. It can be formed directly without CNC.
2. Much cheaper than impregnated carbon.
3. The total thickness can be as low as 2mm.

 

Sintered Carbon Bipolar Plates:

1. Pure carbon, no resin, no resin impregnation, no pores, density 1.80.
2. It can be used above 500℃.
3. Depending on the size, small size can be formed directly, large size may need CNC machining.

 

If you have any questions, please feel free to contact me.
