Joint effort aims to improve critical aspect of fuel cell technology, enhancing system functionality, reliability, performance, and end-user features

Milan / Cambridge, Mass., December 20, 2002 – Nuvera Fuel Cells, Inc., a leading global designer and developer of fuel cell and fuel processing technology, and BWT (Best Water Technology) AG, Europe's market leader in water technology, today announced an agreement to develop a new polymeric membrane suitable for "industrial" fuel cell applications. The joint effort, which commences immediately, will focus on developing and demonstrating an improved membrane to operate in a PEM (proton exchange membrane) fuel cell at temperatures above 90 degrees centigrade.

According to the agreement, Nuvera will work with FuMA-Tech, a BTW subsidiary that specializes in developing fuel cell membranes, to identify multiple prototype samples that meet the project's technical goals. A second phase of the program will involve qualifying the best performing prototypes and preparing MEA's (membrane electrode assemblies) for additional testing and analysis. The two-phased program is expected to last 15 months. In addition, the agreement outlines actions for evolving the collaboration into the commercialization phase.

"High-temperature membranes will foster greater integration in future fuel cell systems," said Michele Tettamanti, Senior Vice President and Chief Operating Officer of Nuvera Europe SrL. "Addressing this key aspect in the product development cycle supports our mission to rapidly enhance the performance of fuel cell technology and increase its value among end-users, such as providing improved co-generation features."

"As a leading innovator in the development of unfloridised high-performance polymers, we are pleased to team with Nuvera in the pursuit of optimizing high-temperature membrane technology," said Andreas Weissenbacher, CEO of BWT AG. "We believe our new, proven membrane products, in particular in the area of central water management, will significantly contribute to the success of this project and help demonstrate substantial technological advantages in fuel cell stacks."
