Bac2 has extended the range of products made from its Electrophen conductive polymer to include high-temperature bipolar plates.

High-temperature operation, typically between 180C and 200C, is required to achieve good efficiency in polymer electrolyte membrane (PEM) fuel cells.

The plates are mechanically and electrically stable over 200C.

They will be on show at the Hannover Fair, Germany, from 20-24 April.

Traditional bipolar plates for fuel cells have to be machined to create the channels through which fuel, air and water vapour flow.

Electrophen is an electrically conductive thermoset material, made from readily available bulk constituents, which can be compression moulded and cured at room temperature.

Bipolar plates based upon Electophen do not need further machining, so they can be produced quickly and economically in any quantity.

High-temperature versions are subject to a conditioning process, but this does not add significant cost or production time.

Electrophen is a conductive polymer that requires relatively little loading with graphite to achieve the required conductivity for fuel cell plate applications.

In addition to offering customised plates in high volume, Bac2 markets blank plates that customers can machine for prototyping work before committing to mould tooling expense.
