Bac2 demonstrates scalable, low-volume production method for moulded polymer bipolar plates

Bac2 demonstrates scalable, economical, low-volume production method for moulded polymer bipolar plates.

Mould-flow characteristics of ElectroPhen® conductive polymer simplify processing and cut manufacturing costs.

Southampton, UK, March 8th, 2011: Bac2, the advanced polymers and fuel cell components company, will be showing moulded bipolar plates for fuel cell stacks on booth D74, Hall 27 at Hannover Messe, 4th – 8th April, 2011. The plates, made using the company’s patented ElectroPhen electrically conductive polymer, reduce the cost of fuel cells because they can be moulded for high volume production. It is economical to tool-up and mould relatively small quantities of plates, sometimes just a few hundred, in order to realize economies of scale. Furthermore, the unique mould-flow properties of ElectroPhen mean that the plates do not need post-processing, such as surface machining or drilling, after moulding. Materials wastage is therefore minimal.
ElectroPhen bipolar plates are available for high-temperature and low-temperature polymer electrolyte membrane (PEM), direct methanol, alkali and phosphoric acid fuel cell stacks.
Unlike those made from metal, the plates are chemically inert, do not corrode, will not poison fuel cell electrodes and are rugged enough to withstand the harshest environments. They are made using a simple, 2-stage, mix-and-mould manufacturing process.

In addition to moulded plates, Bac2 supplies blank plates that can be easily machined for fuel cell development work. Blank plates are available from stock.

Editors’ notes
Bac2 develops advanced composite materials and components derived from these materials.
ElectroPhen® is a low-cost, electrically conductive plastic from which the company manufactures conductive plates for fuel cells. ElectroPhen is also available as a raw material for other electrical and electronic applications.
The CSR family of latent acid catalysts gives better control of pre-polymeric mixes, allowing them to be mixed, stored and then cured at low temperature. This reduces the energy needed in a wide variety of manufacturing processes and cuts costs.
Bac2 has customers in Europe, North and South America, and Asia and the applications for its innovative materials expand with each new development.
