EATONTOWN, N.J.--Millennium Cell Inc. (NASDAQ:MCEL) announced today that the U.S. Department of Transportation ("DOT") issued a notice of proposed rulemaking (NPRM) proposing to permit the transportation in carry-on baggage on passenger aircraft of micro fuel cell systems which utilize sodium borohydride fuels being developed by Millennium Cell to power consumer electronic devices. Millennium Cell is in discussions with a number of consumer electronics OEM's regarding potential products and these new regulations will allow convenient consumer mobility.

This NPRM is part of the DOT's ongoing process of harmonizing US and international regulations, and was expanded (beyond the current scope of the international regulations) to include fuel types used in Millennium Cell's hydrogen batteries. This expansion was a result of a petition for rulemaking submitted by Millennium Cell on August 23, 2006. The rule requires that fuel cell cartridges and systems conform to design and performance standards issued by the International Electrotechnical Commission. In addition, the notice proposes to allow up to three fuel cartridges per passenger carried onto the aircraft.

"The proposed rulemaking by the U.S. DOT is a significant step forward towards the use of Hydrogen on Demand(R) fuel cartridges in micro fuel cell powered consumer devices," said Adam P. Briggs, Millennium Cell President. "We have taken a leadership role in the development of these codes and standards that enable consumers to carry products onto passenger aircraft. This is a very important step in our goal to commercialize hydrogen batteries for consumer electronics applications."
