                 MILLENNIUM CELL REPORTS SECOND QUARTER RESULTS
                    ~ Reduces Net Loss and Cash Consumption ~
    ~ Intensifies Focus on Battery Replacement Solutions for Target Markets ~

Eatontown, NJ--July 27, 2004 --Millennium Cell Inc. (NASDAQ: MCEL), a leading
technology development company which offers a proprietary technology to safely
store, generate and deliver pure hydrogen as an energy source, today reported
results for the second quarter ended June 30, 2004.

The net loss for the second quarter of 2004 was $2.9 million, or $0.08 per
share, compared to a net loss of $4.1 million, or $0.13 per share, in the same
period last year. The reduction in net loss from 2003 is a direct result of
ongoing cost containment activities and the favorable impact of programs with
the U.S. Air Force and the U.S. Department of Energy.

Cash used in operating and investing activities during the second quarter of
2004 declined to $1.3 million from $2.7 million in last year's second quarter.
In the first six months of 2004, cash used was $3.4 million, down from $5.8
million in the prior-year period.

"Our financial results for the period reflect our success in managing the cost
side of the business as we work towards commercialization of our technology,"
said H. David Ramm, Millennium Cell Interim President and CEO. "We are
intensifying our focus on attractive near-term markets while maintaining a
presence in the longer-term transportation market. In the areas of consumer
electronics, portable power, and standby power, we have identified specific
battery replacement opportunities for our Hydrogen on Demand(TM) ("HOD")
systems. In these markets, we believe the value proposition of our technology,
when paired with a fuel cell, can exceed that of traditional batteries in terms
of energy density, cost, and weight."

Mr. Ramm continued, "As part of our shifting focus, we are working to establish
partnerships in key markets over the next several months that will result in the
development of commercial prototypes for manufacture. In the consumer
electronics market, our target is to select a partner and develop an integrated
HOD/PEM fuel cell power device that demonstrates our technology as a reliable
power source for personal computers. In the portable power market, we are making
progress through our existing partnership with Protonex Technology Corporation
to provide the U.S. Air Force with a lighter, longer-lasting power solution to
replace traditional batteries. We currently plan to demonstrate the first
prototype of this technology in early 2005."

A conference call to discuss our second quarter results that will be
simultaneously Webcast is scheduled for July 28th, at 9:00 a.m., EDT. Interested

financial measure to compare to prior periods as it is a better indicator of
cash spending and is also how its management views the business internally.
