Ballard Announces Supply Agreement for Fuel Cell-Powered Lift Truck Market.

VANCOUVER, British Columbia -- Ballard Power Systems (TSX:BLD)(NASDAQ:BLDP) today announced that is has signed an Equipment Supply Agreement ("ESA") with Cellex Power(TM) Products, Inc. ("Cellex") to deliver 27 Mk 902 4.8 kilowatt fuel cells to Cellex for integration into its power units for its upcoming beta trials. Cellex's power products are designed to replace industrial lead acid batteries in electric lift trucks used in high throughput distribution centers.

"Our decision to focus our efforts on fuel cell development, leaving systems integration to others, is beginning to bear fruit. The flexibility of our Mk 902 fuel cell platform, which was developed for automotive applications, enables us to meet our customers' needs in multiple markets," said Noordin Nanji, Ballard's Vice President, Marketing and Business Development. "We are excited to see this technology applied to the industrial vehicles market and look forward to supporting Cellex in the successful implementation of field trials."

Chris Reid, Cellex's President and CEO said, "After evaluation testing of the Mk 902, Cellex is pleased to have an ESA in place with Ballard as an important part of its product solution to its customers." Reid went on to say, "Cellex's products add value to battery powered lift truck fleets by increasing productivity, reducing labour costs associated with changing batteries and improving the workplace environment by eliminating the handling of lead and acid on a daily basis."

Ballard expects to begin unit deliveries in the third quarter of 2005. The term of the ESA expires in the third quarter of 2006. If the field trials are successful, Ballard and Cellex intend to negotiate a follow-on supply agreement to support higher volumes in 2007 and beyond.
