QuestAir Delivers Hydrogen Purification Units to Plug Power, BHK.

QuestAir Technologies Inc. has delivered the first of 10 H-3200 hydrogen purification units to Plug Power Inc. to be integrated into Plug Power GenSite™ hydrogen generation systems that will operate at customer sites at international locations.  This delivery follows a successful one-year field trial of QuestAir’s H-3200 hydrogen purifier at Plug Power’s Apeldoorn facility in the Netherlands.  During the verification trial, the H-3200 has been integrated with a prototype GenSite™ system and has operated for more than 3,000 hours, producing 99.95% pure hydrogen.  A H-3200 hydrogen purifier has also been installed by Babcock Hitachi K. K. (BHK) at the Oume Hydrogen Station in suburban Tokyo, the world's first mobile hydrogen fueling station that produces hydrogen from natural gas. The station will provide hydrogen fuel for fuel cell vehicles in a number of locations and is the second Japanese hydrogen fueling station to install QuestAir's hydrogen purification technology. http://www.questairinc.com/investor_relations/press_releases/archived_releases/2004/08-17.htm
