At the Fuel Cell Pavilion at the Hannover Messe 2008, British company Bac2 has announced that it's introducing blank bipolar plates for polymer electrolyte membrane (PEM) fuel cells made from their proprietary polymer, called ElectroPhen. This allows easy prototyping because they're easier to produce and thus 30 percent cheaper than metal plates.

According to Bac2, the plates exceed the U. S. Department of Energy specifications for use in automotive applications. Bac2 also claims that material has a raw state conductivity one billion times higher than commonly used resin binders, which means that no post-processing is needed. You can also adapt it in any shape or with almost any material to make your own fuel cell.
