Nuvera Signs Agreement to Purchase Hydrogen Purification Systems from QuestAir

Cambridge, Mass., June 1, 2006 – Nuvera Fuel Cells (“Nuvera”) has signed an agreement with QuestAir Technologies Inc. (AIM: QAR; TSX: QAR) to purchase H-3300 hydrogen purifiers through 2008. Nuvera will receive an initial delivery of the H-3300 units later this year.

Under the terms of the preferred supplier agreement, QuestAir’s H-3300 pressure swing adsorption (“PSA”) systems will be integrated into Nuvera’s PowerTapTM branded hydrogen generators. The PowerTapTM converts widely available fuels such as natural gas and liquefied petroleum gas (“LPG”) to hydrogen. QuestAir’s H-3300 will purify the hydrogen product to the demanding purity specifications required for fuel cell markets.

Roberto Cordaro, President and CEO of Nuvera Fuel Cells said, “QuestAir has a demonstrated track record in the supply of market-leading hydrogen purification systems, and has met or exceeded product specifications and delivery schedules on PSA systems supplied to Nuvera to date. QuestAir’s H-3300 PSA system offers superior performance and a compact design which is ideally suited to the requirements of our PowerTap hydrogen generator.”

Jonathan Wilkinson, President and CEO of QuestAir said that Nuvera’s PowerTap hydrogen generator will provide hydrogen fuel for fuel cell powered industrial vehicles such as forklifts and airport ground support vehicles.

“Fuel cells offer a compelling value proposition as a replacement for lead acid batteries in forklifts and other industrial vehicle, and we expect that these markets will be aggressive early adopters of fuel cell technology.”

“The supply of cost-effective hydrogen fuel at the distribution centers or work sites where these vehicles are used is clearly a challenge. Nuvera’s PowerTap hydrogen generator, including QuestAir’s H-3300, provides a compact, cost effective solution for the distributed generation of this hydrogen fuel,” said Wilkinson.

In 2004 Nuvera launched the PowerFlowTM range of fuel cell power modules for industrial vehicles used in material handling, airport ground support, turf care, construction and forestry. The PowerTap hydrogen generator will be offered as an integrated solution for generating and dispensing hydrogen fuel to customers and users of Nuvera’s PowerFlow fuel cell products.

QuestAir’s H-3300 PSA product offers a compact and low cost hydrogen purification solution for small capacity hydrogen generation systems. The H-3300 incorporates QuestAir’s proprietary PSA process and rotary valve technology, and has hydrogen product capacity of up to 30 normal cubic meters per hour (NCMH), at hydrogen product purities of 99.999% or greater.
