Ballard to Demonstrate Fuel Cell Technology in Three Distinct Backup Power Generation Applications

Government of Canada to Provide Funding for Fuel Cell Demonstration Projects

VANCOUVER, British Columbia, Sep 27, 2004 (BUSINESS WIRE) --

Ballard Power Systems (Nasdaq:BLDP) (TSX:BLD) announced it will demonstrate three distinct applications utilizing Ballard(R) fuel cells for backup power in cooperation w
ith the Government of Canada under the h2 Early Adopters (h2EA) Program. The h2EA Program will fund Cdn. $2 million of the $4 million program with the balance of funding to be provided by the program participants. Field demonstrations such as this support the Canadian Government's aim to accelerate the development of a hydrogen economy by encouraging innovation, expanding industrial capacity, and meeting climate change objectives.

The demonstration will involve projects to demonstrate Ballard(R) fuel cell technology for uninterruptible power supply and backup power applications for the power generation market. Ballard will lead the program with support and participation by MGE UPS Systems, Bell Canada Holdings, Emerson Network Power Canada, Praxair Distribution and the University of Toronto at Mississauga. These innovative, real-world applications of hydrogen fuel cell technology are key to identifying and facilitating the development of the necessary codes and standards to commercialize fuel cell and hydrogen technology, such as siting and permit requirements.

"The Government of Canada's continued support is helping to accelerate fuel cell technology in Canada through demonstrations like this, providing momentum for the development and market introduction of fuel cells and hydrogen technology," said Dave Smith, Chief Financial Officer of Ballard Power Systems. "The benefits to be gained from this project are wide-ranging: establishing channels to market, refining the Nexa(R) RM product, advancing siting and permit requirements, increasing public awareness across all stakeholder groups and generating valuable field data with regard to fuel cell operation in diverse power generation applications."

Ballard(R) fuel cell-powered generators will be featured in three distinct applications:

1. As a backup power source for uninterruptible power supply ("UPS") applications at the National Research Council's Institute for Fuel Cell Innovation in Vancouver, British Columbia. Ballard's Nexa(R) RM Series fuel cell modules will be utilized in conjunction with UPS technology from MGE UPS Systems for providing backup power for critical loads in an industrial/commercial building.

2. As a backup power source for a telecommunication site operated by Bell Canada. Ballard's Nexa(R) RM Series fuel cell modules will be utilized in a four-seasons outdoor enclosure supported by Emerson. Praxair Distribution will provide hydrogen fuel supply hardware and hydrogen gas for the duration of the trial.

3. As a backup power source for UPS applications at the University of Toronto at Mississauga. Ballard's Nexa(R) RM Series fuel cell modules will be utilized in conjunction with UPS technology from MGE UPS Systems for providing critical backup power for server room applications at the University. Praxair Distribution will provide the hydrogen fuel supply systems and hydrogen gas delivery to the server room application.
