Bipolar Plates
Bipolar Plates,Used in DMFC and PEMFC systems, as well as redox
flow cells
Our bipolar plates for fuel cells were developed for the heavily
fluctuating PEMFC (Proton Exchange Membrane Fuel Cell) and DMFC
(Direct Methanol Fuel Cell) markets. Through intensive research, we
have been able to combine cost-effective production with
outstanding material properties. Both are valued by leading fuel
cell manufacturers across the globe, a fact reflected in the more
than 700,000 plates produced to date. Our bipolar plates are
characterized by a very high proportion of graphite, which achieves
outstanding electrical conductivity, as well as corrosion
resistance, mechanical strength and flexibility.

You benefit from these advantages:
A unique level of development in material expertise and molding
technologies
Used in DMFC and PEMFC systems, as well as redox flow cells
Can be produced as blanks, milled versions and PTS variations,
according to the customer's wishes
Prototype production possible
Features:
Excellent thermal durability
Good thermal conductivity
Resists wetting by molten metals
Complex shapes can be processed
Reduces metal sleeve weight
Various surface modifications and treatments enable a variety of
applications
Due to its ability to resist wetting by molten metals, graphite is
used as a mold material for strip dies, tubular dies, and other
molds used in continuous casting processes for copper and copper
alloys (brass, bronze, and nickel silver), aluminum alloys, cast
iron, precious metals, and a variety of other metals.
Graphite can be used with different continuous casting methods
(horizontal/vertical) and can be produced in a variety of ingot
shapes (including plates, strips, pipes, rods, wire, and contoured
shapes).
With a wide range of grades available, we can select the optimal
grade for a variety of cast metals and alloys.
We manufactures products from structural brands of graphite,
impregnated graphite, antifriction graphite
Graphite has unique properties:
electrical conductivity;
heat resistance (sublimation effect);
poor wettability by many metals;
strength, anomalously increasing with temperature increasing;
possibility to work with dry friction (self-lubrication)
Due to its unique properties, graphite products are used in many
industries:
production of ferrous, non-ferrous and precious metals;
engineering;
chemistry, petrochemistry and oil refining;
glass industry;
analytical laboratories;
power engineering and electrical engineering.
