QuestAir and FuelCell Energy to evaluate production of pure hydrogen from Direct
                            FuelCell(R) power plants

BURNABY, B.C. - QuestAir Technologies Inc. (AIM: QAR; TSX: QAR), a developer and
supplier of advanced gas purification systems for refinery, industrial and fuel
cell markets, announced today that it has signed a memorandum of understanding
(MOU) with FuelCell Energy, Inc. (NasdaqNM: FCEL) to evaluate the use of
QuestAir's hydrogen purification technology to produce pure hydrogen from the
exhaust of FuelCell Energy's Direct FuelCell(R) (DFC(R)) power plants.

FuelCell Energy, Inc., based in Danbury, Connecticut, is a world leader in the
development and manufacture of high temperature fuel cells for clean electric
power generation. The company's large stationary fuel cell power plants are
installed at more than 36 commercial and industrial sites around the world.

QuestAir and FuelCell Energy will complete a preliminary design and economic
analysis of a system including QuestAir's commercial hydrogen purification
products to produce pure hydrogen from the anode exhaust of a One Megawatt
Direct FuelCell power plant. Direct FuelCell power plants equipped with this '
hydrogen export' system could be used by FuelCell Energy's customers to produce
pure hydrogen for industrial uses or to fuel fleets of fuel cell vehicles, in
addition to generating electrical power and heat. Under the terms of the MOU,
QuestAir and FuelCell Energy will also cooperate to secure funded demonstrations
of this hydrogen export system.

The companies will also undertake a technical and economic assessment of the use
of QuestAir's advanced gas purification technology to recover and recycle
hydrogen within the Direct FuelCell power plant. Such a 'hydrogen recycle'
system has the potential of increasing the electrical efficiency of the Direct
FuelCell power plants, which would reduce the net cost of electrical power
produced by the fuel cell.

"QuestAir's advanced hydrogen purification technology has the potential to add
significant value to FuelCell Energy's plants by producing a purified hydrogen
by-product, and by increasing the overall efficiency of the fuel cell power
plant," said Jonathan Wilkinson, President and CEO of QuestAir. "We look forward
to completing this initial phase of the product development, and securing a
demonstration site for a Direct FuelCell equipped with a prototype hydrogen
export system."

"The trigeneration of hydrogen as well as electricity and heat by our DFC power
plants further enhances the value proposition for many of our targeted customer
segments," said Dr. Hansraj C. Maru, Chief Technology Officer of FuelCell
Energy.  "This demonstrates the versatility of our 'ultra-clean' DFC products
for the developing fuel cell market."

Each company will cover its own expenses for work completed under the MOU, which
is expected to be complete by the fourth quarter of 2005. At that time QuestAir
and FuelCell Energy will decide whether to proceed with further product
development and testing.
