The company was founded in 2002 to commercialize an advanced Reformed Methanol Micro Fuel Cell (RMFC) technology invented at the U. S. Department of Energy's Lawrence Livermore National Laboratory (LLNL). This technology enables a breakthrough in micro fuel cell performance. UltraCell is the first to commercialize RMFC technology to provide clean renewable energy to power portable electronics. UltraCell's XX25™ micro fuel cell system is leading the industry with its ultra-compact size and light weight. The XX25 is the only system in its class to have undergone extensive Military Specification qualification testing and field trials.

UltraCell's team has extensive experience in all aspects of fuel cells, including research, product development, manufacturing and customer applications. The company has developed new technologies and intellectual property in the field of methanol-based fuel cells and continues to innovate in this rapidly emerging field. UltraCell has an exclusive license with LLNL for micro fuel cell technology based upon reforming methanol into hydrogen reformate using proprietary technology in the fuel reformer and hydrogen fuel cell stack.
