Huntsman to Develop New Resin for Fuel Cell Production

THE WOODLANDS, Tex., January 12, 2007 -- Huntsman Advanced Materials announced today that it is working in partnership with GrafTech International (NYSE: GTI) subsidiary Advanced Energy Technology (AET) to develop a new binder formulation for use in bi-polar plates that comprise fuel cells for automotive and military vehicles. Based on patented AZYRAL® halogen-free resin chemistries, the new binder formulation will play an integral role in supporting the objective of developing fuel cells that are both cost-effective to manufacture and durable in service. Funding for the fuel cell program was awarded by the U.S. Department of Energy to a consortium of companies. In addition to AET and Huntsman Advanced Materials, project partners include Ballard Power Systems and Case Western Reserve University.

The AZYRAL resin-based binder now being formulated will be used with AET's GRAFCELL® expanded natural graphite to create corrosion-resistant, lightweight flow-field plates aimed at Proton Exchange Membranes (PEM) fuel cell technology. Like other products in the AZYRAL product family, the new resin will be a halogen-free material with a low viscosity to accommodate automated application. The resin will also combine a low dielectric constant and low dissipation factor with good surface and volume resistivity as well as good high-temperature stability for reliable, long-lasting fuel cell operation.

Once completed, the new GRAFCELL® bi-polar plates will be evaluated by Ballard Power System for use in fuel cell stacks. Case Western Reserve University has been granted funding to conduct comprehensive testing on the new products.

Huntsman anticipates that the new binder will work in synergy with the physical performance capabilities of GRAFCELL® natural graphite and AET's efficient, economical manufacturing processes to produce fuel cells that will power pollution-free cars of the future.
