For Immediate Release – November 17, 2011

VANCOUVER, CANADA – Ballard Power Systems (TSX: BLD) (NASDAQ: BLDP) will be providing fuel cell modules to power two new fuel cell hybrid buses, funded under the Federal Transit Administration's (FTA) "Transit Investments for Greenhouse Gas and Energy Reduction (TIGGER) Program". As per today's announcement by the FTA, Ballard will work together with consortium partners BAE Systems and ElDorado National (California) to deliver these buses to SunLine Transit Agency in Thousand Palms, CA.

The TIGGER Program works directly with public transportation agencies to implement new strategies for reducing greenhouse gas emissions and lowering energy use within transit operations. Through this Program, the FTA is playing a key role in accelerating fuel cell bus deployments, providing greater public exposure to the safe operation of zero-emission vehicles and encouraging broader acceptance of the technology.

Bill Foulds, Ballard's President of U.S. Operations said, "Earlier this week the very first All-America fuel cell-powered bus, using a Ballard module, was unveiled by SunLine Transit Agency and FTA Deputy Administrator Therese McMillan. The additional funding announced today by the FTA to grow SunLine's fuel cell bus fleet is further validation of our Buy America-compliant technology."

Under this new award, Ballard will supply FCvelocitytm-HD6 power modules for ElDorado fuel cell hybrid buses featuring a series hybrid electric drive from lead integrator BAE Systems. It is anticipated that these buses will be operational in 2013, bringing the total number of Ballard-powered buses in use at SunLine Transit to four.

Ballard's fuel cell module is a ‘plug-and-play' product that permits system integrators to readily build clean energy buses at reduced cost. The fuel cell module incorporates sub-system components for humidification, hydrogen pressure regulation, hydrogen recirculation, water management, ventilation and controls.

Ballard's Lowell, MA facility manufactures FCvelocityTM-HD6 fuel cell modules for the U.S. market. Highly innovative, zero-emission fuel cell buses are expected to play a critical role in the future of transit, preserving non-renewable energy sources and substantially reducing the environmental footprint.
