FUEL CELL BIPOLAR PLATE

However, bipolar plates obtained by above method (1) are manufactured by molding a mixture of graphite powder, thermoset resins such as phenolic resin and epoxy resin, and carbon fibers. Hence, the resulting bipolar plate has an improved strength, but it also has a much higher modulus of elasticity, as a result of which it has a tendency to break when given a thin-walled construction.

Composites fuel growth of fuel cell technology

To make the "resin-reinforced" GRAFCELL in bipolar plates as thin as 0.024 inch/0.6mm, naturally inert crystalline graphite flakes are chemically treated and heated. This causes expansion of the flakes into worm-like shapes that are then compressed into a flat sheet of flexible graphite that is subsequently impregnated with resin to form a continuous, compression moldable prepreg sheet.

Improvement of electrical resistivity of highly filled

Novel material solutions for polymer based bipolar plates in fuel cells require adapted ways to develop suitable material compositions. The common pathway to develop materials with at the same time high electrical as well as thermal conductivity is the use of conductive graphite as filler with contents up to 80-85 wt.%. However, there is a need to develop recipes with maximized conductive
