For Immediate Release

VANCOUVER, CANADA - Ballard Power Systems (NASDAQ: BLDP; TSX: BLD) today announced that it has signed an agreement to provide a 1 megawatt (1MW) ClearGen™ fuel cell distributed generation system for Hydrogène de France (HDF) which will be deployed at an AkzoNobel (www.akzonobel.com) sodium chlorate chemical plant in Bordeaux Métropole, France. In addition, Ballard will provide engineering services support for the program.

Kevin Colbow, Ballards Vice President, Technology Solutions said, "This Technology Solutions transaction is another demonstration of Ballards competency in addressing customer needs in a variety of application areas. This program will benefit from our experience with the one megawatt ClearGen™ system that has been successfully operating to provide peak power at Toyotas Torrance California campus over the last two years."

Powered by its proprietary proton exchange membrane (PEM) fuel cells, the Ballard ClearGen™ clean energy system will enable HDF to generate electricity and supply it to the local grid, helping satisfy local power demands.

The ClearGen™ system is suitable for locations that have a demand for clean energy, high incumbent utility rates, and a ready source of hydrogen; potential customers include chemical producers, remote communities and utilities with a renewable power mandate. In the case of AkzoNobel, production processes used at its chemical facility in Bordeaux Métropol generate by-product hydrogen which will be used to fuel the ClearGen™ system.

The program announced today will be partially funded by the EU Fuel Cells and Hydrogen Joint Undertaking (FCH-JU), with the remaining funding to be provided by HDF and its partners. The FCH-JU is supporting this program to help define EU standards of fuel cell integration and to validate progress made in increasing stack life.

The program agreement is structured in two phases. Under the first phase, targeted for completion in mid-2016, Ballard will receive an initial payment of €1.7 million to undertake engineering services and core component development work. Under the second phase, targeted for completion in 2017, Ballard will receive an additional €1.7 million for onsite assembly and commissioning, subject to Hydrogène de France securing necessary funding to complete the project.
