UltraCell Corporation has developed 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 micro reformer to generate fuel-cell-ready hydrogen from a highly concentrated methanol solution.
The portable power system weighs in at just 40 ounces and is about as big as a paperback novel.
The system’s spent fuel canisters can be instantly “hot swapped,” as needed, to provide continuous power in any remote situation.
A complete UltraCell system includes fuel processor, fuel cell stack, control system and a replaceable fuel cartridge. Based on proprietary control algorithms, the control system manages a steady flow of power by adjusting pump and compressor settings.
The micro fuel cell generates no excess water, and consequently does not need a water management system, saving size, weight and cost versus alternative micro fuel cell systems.
In addition, the system uses a high temperature membrane assembly (MEA) from Pemeas in its fuel cell stack, resulting in high tolerance to CO and impurities.
MOF captures hot CO2 from industrial exhaust streams
How much so-called "hot" exhaust could be usefully captured for other heating purposes (domestic/commercial) or for growing crops?
