   QuestAir signs agreement to supply hydrogen purification systems to Nuvera


VANCOUVER, B.C. - QuestAir Technologies Inc. (AIM: QAR; TSX: QAR) has signed an
agreement, valued at up to US$700,000, to supply its H-3300 hydrogen purifiers
to Nuvera Fuel Cells ("Nuvera") through 2008. QuestAir also received a purchase
order from Nuvera for initial delivery of 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 PowerTap(TM)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.


Jonathan Wilkinson, President and CEO of QuestAir said that Nuvera's PowerTapTM
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 vehicles, 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 PowerTapTM
hydrogen generator, including QuestAir's H-3300, provides a compact, cost
effective solution for the distributed generation of this hydrogen fuel," said
Wilkinson.


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(TM)hydrogen generator."


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