ECD Ovonics Subsidiary Ovonic Fuel Cell Company Awarded Grant by Michigan Public Service Commission

ROCHESTER HILLS, Mich., Aug. 24, 2005 -- Energy Conversion Devices, Inc., (ECD Ovonics) , announced today that Ovonic Fuel Cell Company LLC, its wholly owned subsidiary, has been awarded a $400,000 grant by Michigan Public Service Commission. This Michigan Energy Efficiency Grant will support a nine-month program for the development of a prototype fuel cell system for uninterruptible power supply (UPS) and emergency power applications.

In a fundamentally new approach, the Ovonic Metal Hydride Fuel Cell technology includes a unique and inherent ability to store electrical energy in the fuel cell stack. This intrinsic energy storage provides for several key performance features ideal for UPS/emergency power applications, including instant-start capability on the order of microseconds and excellent low- temperature performance. The Ovonic fuel cell technology provides a low-cost approach based on Ovonic metal hydride materials and does not utilize expensive noble metals traditionally used as fuel cell catalysts.

In today's world, with concerns about power interruptions from extreme weather, acts of terrorism, and failures of our aging electrical grid, there is a growing need for power backup for extended run time emergency situations. The Ovonic fuel cell technology is especially well suited for this growth opportunity in the multibillion dollar UPS/emergency power market. This program will enable Ovonic Fuel Cell Company to provide prototype fuel cell products to a variety of interested customers.
