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 its H-3200 hydrogen purifier has been
installed at the Chevron Hydrogen Energy Station located in Chino, California.
The station, which was unveiled on 18 February 2005, is the first of up to six
hydrogen energy stations to be constructed in California by ChevronTexaco
Hydrogen Company under the U.S. Department of Energy (DOE) "Controlled Hydrogen
Fleet and Infrastructure Demonstration and Validation Program".



The hydrogen energy station is part of a five-year DOE cost-sharing program to
demonstrate the use of safe, practical hydrogen and fuel cell technologies in
real world operating conditions. The project is being led by ChevronTexaco
Technology Ventures.



The hydrogen energy station demonstrates the generation of hydrogen fuel from
natural gas at the service station. QuestAir's H-3200 purifies hydrogen produced
from natural gas using proprietary small-scale hydrogen production technology
developed by ChevronTexaco Technology Ventures LLC. Purified hydrogen from the
station is used to fuel a fleet of fuel cell powered sport utility vehicles.



"We are extremely pleased to provide QuestAir's hydrogen purification technology
and expertise to this high profile DOE funded project," said Jonathan Wilkinson,
President and CEO of QuestAir, "California is leading the world in the
construction of hydrogen fueling infrastructure to support the demonstration of
fuel cell vehicle fleets, with 24 stations either planned or already in
operation."



QuestAir's H-3200 purifies gas streams containing hydrogen to high-purity
hydrogen for use in industrial processes, hydrogen fueling stations and
stationary fuel cell power plants. The H-3200's optimized Pressure Swing
Adsorption (PSA) process and proprietary rotary valve technology deliver higher
efficiency than conventional PSA systems in a more compact, cost-effective
package. Since the product launch in 2003, QuestAir has sold 24 H-3200 systems
to customers in Europe, Japan and North America.
