Bipolar Graphite Plate, graphite bipolar plate for hydrogen fuel cell

Short Description:

Bipolar plates (BPP) are a key component of Proton Exchange Membrane (PEM) fuel cells. Due to its high efficiency, low-temperature operation, high power density, fast start-up, and system robustness. Bipolar plate is a vital component of PEM 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.

Product Detail

Product Tags

Bipolar plates are core components of PEM fuel cells. They control not only hydrogen and air supply but also the release of water vapor, along with heat and electrical energy. Their flow field design has a major impact on the efficiency of the entire unit. Each cell is sandwiched between two bipolar plates – one letting in hydrogen on the anode and another air on the cathode side – and produces about 1 volt under typical operating conditions. Raising the number of cells, like doubling the number of plates, will increase the voltage.Most PEMFC and DMFC bipolar plates are made of graphite or resin-impregnated graphite.
