The hot-swappable, light weight UltraCell25 fuel cartridge, currently in development by UltraCell, will be able to power an average mobile computer for an entire day.
August 24, 2005 UltraCell Corporation has announced a new fuel cell power source for portable electronic devices that has twice the energy density of lithium batteries. UltraCell's reformed methanol fuel cell (RMFC) technology uses a revolutionary micro reformer to generate fuel-cell-ready hydrogen from a highly concentrated methanol solution. This new portable power system has the power density of a hydrogen fuel cell but uses readily available, low cost methanol fuel in a convenient, compact package. Weighing just 40 ounces, the power unit is about the size of a paperback novel.
