Millennium Cell to Demonstrate New Hydrogen Fuel Option for Jadoo Power Fuel Cells.

Chemical Hydride Reduces Fuel Storage Weight By 50%

EATONTOWN, N.J. -- Millennium Cell Inc. (NASDAQ: MCEL), a leading developer of hydrogen battery technology, announced today that they will be demonstrating a new chemical hydride fueling option for the Jadoo Power line of portable fuel cell products at the upcoming Battery and Fuel Cell Technology for Portable Devices Conference. The conference will be held at the AMA Conference Center in Chicago, IL from September 26-28, 2006. The new fuel solution will utilize Jadoo's N-Stor interface and be fully compatible with all Jadoo products including the recently announced XRT fuel cell system.

The XRT is a 100 W, 110VAC / 12VDC power support system. With over 2200 W-hr runtime, the XRT is ideal for off-grid mission critical applications such as first responders and surveillance. The XRT currently uses six metal hydride canisters for fuel storage which weigh approximately 30 total pounds. With the new jointly developed chemical hydride based fuel canister, the XRT will deliver the same runtime with half the fuel canister weight.

Mr. Adam Briggs, Millennium Cell's President stated, "In less than six months time, our engineering teams have developed the first prototype incorporating our technology with Jadoo Power Systems. This clearly demonstrates the potential of this collaboration and we are anxious to pursue other opportunities for commercialization."

The XRT is all about flexibility", said Larry Bawden, President and CEO, Jadoo Power. "Customers can choose from the latest technologies that suit their application. This jointly developed fuel option represents the future of energy storage technology.

The device will be shown alongside other solutions under development by the company's licensees at the Battery and Fuel Cell Technology for Portable Devices Conference and the pre-conference workshop entitled, "Examining Hydrogen Battery Technology for Portable Applications."
