Business Editors

Ballard Power Systems Inc. (NASDAQ:BLDP) (TSE:BLD) announced today the appointment of Dennis Campbell as President and Chief Operating Officer effective July 22, 2002.

Mr. Campbell comes to Ballard after a 30-year career encompassing all aspects of manufacturing in businesses as diverse as automotive, plastics, power generation, helicopters, specialty compressors, and filter systems. He is joining Ballard from Home Care Industries, a leading filter system manufacturer where he was President and Chief Executive Officer. Before that he held positions with Nash Engineering (President and Chief Executive Officer), United Technologies (Executive Vice President, Sikorsky Aircraft), Cummins Engine Company (Vice President, Power Generation Group, Onan Corporation), and Plastech Corporation (President and Chief Operating Officer). Mr. Campbell began his career in 1970 with the Ford Motor Company, starting in product development, progressing through a series of operating assignments in the Engine, Tractor, Climate Control and Plastics businesses.

As part of Ballard's management succession plan, Mr. Campbell will take on the position of Chief Executive Officer on March 31, 2003, when Firoz Rasul will become Executive Chairman of the Board of Directors.

Mr. Campbell brings to Ballard a vast amount of commercial experience that directly applies to Ballard's fuel cell and related businesses in the portable, stationary and transportation power markets. He is 54 years of age and has a Bachelor of Science in Aerospace Engineering from the University of Oklahoma and a Master of Business Administration from Wayne State University.

"We are pleased to welcome Dennis Campbell to the Ballard team as President and Chief Operating Officer," said Firoz Rasul, Ballard's Chairman and Chief Executive Officer. "As Ballard is evolving to become a commercial manufacturer of fuel cell products it is undergoing dramatic change. In the past 12 months, Ballard has made three major acquisitions, is completing a major reorganization, and is now focused on commercial product introduction. Dennis' experience and capabilities in product development, manufacturing, business processes and building lasting customer relationships, match the requirements to lead Ballard into its next stage - mass commercialization. As a result, Dennis will succeed me as Chief Executive Officer next year to drive this change and lead Ballard going forward."

Mr. Rasul continued, "As future Executive Chairman of the Board I will continue to lead the Board of Directors to provide the resources and mandate to the Chief Executive Officer to carry out Ballard's strategic plan and vision. As Executive Chairman, I will ensure our continued high standards of corporate governance and will work, together with Dennis, to enhance key external relationships with customers, partners, shareholders and governments to meet the needs of our growing business. I remain deeply committed to the mass commercialization of Ballard(R) fuel cells and helping to shape the fuel cell industry."

Dennis Campbell commented, "The opportunity to join Ballard is exciting - not only because fuel cells can solve many of the world's pressing environmental issues - but because of Ballard's ability to become a highly successful business. Ballard has assembled a strong management team, dedicated and talented employees, committed strategic partners, formidable technology position and financial strength, all of which we can use to convert Ballard's leadership position into great commercial success."

Mr. Campbell added, "Over the past 14 years, under Firoz's leadership, Ballard has progressed enormously from a small research and development company to a global leader in fuel cell technology. I am committed to working with Firoz and the Ballard team to build upon Ballard's strengths and deliver even greater success in the coming years."
