Product Description

Fuel Cells

A fuel cell is a device in which electrical energy is generated by the electrochemical reaction between a fuel (H2 or a hydrocarbon) and oxidant. Fuel cells represent the new generation of high efficiency, environmentally friendly energy systems. 
 

Graphite for fuel cells and energy storage systems

Our graphite bipolar plate material is specially selected and qualified for fuel cell, which allows a very high fuel cell performance with very competitive cost. In the past year, we have made around 20,000 pieces of graphite bipolar plates for clients. we are one of leading manufacturer of bipolar plates in China and have been built long term business relationships with clients from USA, Italy, Spain, Germany and other countries globally.

The size and channels of bipolar plate can be customized to machine as per the designs.

Why bipolar plate is so important for fuel cell?
Bipolar plates are a key component of fuel cells, due to its high efficiency, low-temperature operation, high power density, fast start-up, zero emission, low noise. Bipolar plate is a vital component of fuel cells, which supplies fuel and oxidant to reactive sites, removes reaction products, collects produced current and provides mechanical support for the cells in the stack. Bipolar plates constitute more than 60% of the weight and 30% of the total cost in a fuel cell stack. 
 

 

The size and channels of bipolar plate can be customized to machine as per the designs.
Product Advantages:

1. Special plugging process and graphite modifier to ensure zero leakage under operating conditions for more than 20,000 hours
2. Special surface processing technology to ensure contact resistance
3. Exclusively designed and developed large-area bipolar plate, the power per liter is greatly improved
4. Light milling process, the graphite plate can be as thin as 0.5mm (milling on one side)/0.8mm (milling on both sides)
5. good durability, reliability and power density
6. With their excellent corrosion resistance, they offer extreme long-term stability in fuel cells.
7. High electrical conductivity, very good mechanical strength and design freedom.
