Methanol fuel cell powers ruggedized computers

A California company has introduced a 25-watt mobile fuel cell system designed to power a ruggedized laptop computer for up to 14 hours at a time using a single 250cc cartridge.

The XX25, as it is called, internally generates fuel cell-ready hydrogen from a highly concentrated methanol solution, providing power to a field computer and communications equipment at weight savings of up to 65 percent, according to Livermore, Calif.-based UltraCell.

Fuel cells are electrochemical devices that use hydrogen and oxygen to produce electricity, and continue to produce it as long as the fuel lasts. This is not only ecologically … Read more
