Samsung Advanced Institute of Technology (SAIT; CEO: Yoon-woo Lee) and Samsung Electronics Co., Ltd. announced continuous usage of notebook PCs for more than 10 hours without recharging using their fuel cell technology.
Using nano materials technology, SAIT has reduced the amount of catalyst by 50% by developing Mesoporous carbon material, which supports highly efficient nano catalyst particles with 3 nanometers in dimension.
SAIT has developed its unique nano composite concept to prevent methanol crossover by more than 90%. This composite uses a proton conducting membrane that possesses a proton conductivity rate of 0.1S/cm and is 30- to 100-micron in thickness.
Energy efficiency is optimized by a unique stack design that has a parallel fuel supply flow, which, combined with a high-efficient controller and Samsung Electronics' package technology, was successfully applied to Samsung's notebook PCs.
Dr. Hyuk Chang, who is responsible for fuel cell research at SAIT is planning to give an invited talk at the International Conference of Small Fuel Cell (SFC 2004, Arlington, USA) in May this year. SAIT has filed a total of 40 international patent applications for the secured technologies. Dr. Chang stated, "We are planning to do some additional research with Samsung SDI to meet the criteria for commercialization, including energy density and cost, and we are optimistic about the successful application of DMFC in Samsung Electronics' note PC series, including SensQ"." He also revealed, "We aim to replace the portable and residential power supply with fuel cell in the future."
Samsung Advanced Institute of Technology is the corporate central Research & Development organization. It develops innovations and new findings in the areas of digital, nanotechnology, MEMS (Micro Electro Mechanical System), opto, energy, and biotechnology.
