Livermore (CA) – UltraCell, a Livermore, California-based company, recently introduced a 25-watt mobile fuel cell system designed specifically for supply power to a ruggedized laptop computer for military personnel. The XX25 cell provides power for up to 14 hours at a time using only one 250 cc cartridge.

The XX25 generates fuel cell-ready hydrogen internally from a highly concentrated methanol solution. This allows individuals to power their field computers and other communication equipment at a weight reduction of about 65% compared to regular lithium-ion batteries.

Fuel cells use both oxygen and hydrogen to produce electricity with water vapor as a by-product. Additionally, they continuously produce electricity until the fuel source diminishes. Not only is this environmentally conscious but it also weighs less. Because the conversion of the fuel to energy occurs through an electrochemical process instead of through combustion methanol fuel cells are not only cleaner, but also quieter than generators that are powered by gasoline.

UltraCell calculates that during the standard 72-hour military mission every soldier needs about 27 pounds of rechargeable military batteries.

The Army’s Communications-Electronics Research Development and Engineering Center have allowed UltraCell’s development contract to be extended so that further testing on the cell can be performed. A year ago they decided that the 25-watt model was safe enough to be worn and used by military personnel actively in the field so that they could power their portable devices. This is a milestone, and a first among the Methanol Fuel Cell type.

Back in 2006 at the Intel Developer Forum in San Francisco, we saw the UltraCell up close back when it was in prototype stages.

San Francisco (CA) - Imagine being able to power your laptop for two days on a single charge. You may not have to imagine for much longer. Fuel cell manufacturer UltraCell is demonstrating a prototype fuel cell system at the Intel Developer Forum, that it promises will replace conventional laptop batteries. The company's XX25 prototype being designed for the military, as well as a commercial version called the UC25, promise to as much as 9 hours of power within the 20 watt envelope - about double the capacity of current laptop batteries - while weighing up to 70% less.
The UltraCell 25 fuel cell.

UltraCell's fuel cell systems use replaceable cartridges that contain a mixture of 67% methanol and 33% water. The power adapter into which the cartridges fit weighs about one kilogram, while the military versions of the cartridges themselves - which contain 500 wh/kg of energy - weigh 625 grams each. Commercial versions of the cartridges will contain 300 wh/kg of energy and weigh 260 grams each.

While the weight of the military version may seem significant, the company claims the weight of enough fuel cells for a 72-hour mission is 67% less than comparable batteries being used today. For soldiers who often carry their body weight's worth, or more, in gear into the battlefield, any reduction in weight is greatly appreciated.

UltraCell says that military prototypes will be delivered in the second quarter of 2006. The commercial UC25 model will go into beta testing in the second half of 2006. Whether soldiers beta-testing the new batteries will have to make up the lost weight by carrying fire extinguishers on their backs, remains to be seen. only cleaner, but also quieter than generators that are powered by gasoline.
