"We are very excited to have Dantherm as a lead customer for the Mark1020 ACS in the backup power market," said Noordin Nanji, Ballard's Chief Customer Officer. "The company is a highly-respected supplier of complete power supply solutions for fixed and wireless telecommunications mobile networks."

Backup power solutions based on fuel cell technology deliver a number of significant advantages over conventional batteries and diesel generators, including higher reliability over a wide range of operating conditions; lower maintenance costs; longer operating life; and reduced size, weight, installation footprint, and environmental impact. The Mark1020 ACS fuel cell provides all of these advantages to power sub-system integrators, and enables an extremely compact and cost-effective backup power solution with its air-cooled design.

"This agreement with Ballard marks the official beginning of a strong and growing partnership with the leading provider of fuel cell products," said Per Albaek, Managing Director of Dantherm Air Handling A/S. "Dantherm selected Ballard's Mark1020 ACS fuel cell for our products because it is simply the best air-cooled fuel cell on the market today in terms of performance, reliability, and price. Using Ballard's product offering and fuel cell expertise, we provide backup power solutions available for sale today to customers who see the compelling value proposition fuel cell technology provides to the telecommunications market."

This agreement is an important step in Ballard's strategy to build a leading position in the backup power market, along with materials handling and residential cogeneration.
