Researchers Improve Design of Fuel Cell for Consumer Electronics

Briefly Noted

2002-02-25 [] Researchers at Lawrence Livermore National Laboratory in California have developed and demonstrated a laboratory prototype, miniature thin-film fuel cell power source, which provides portable electrical power for a range of consumer electronics. With the LLNL fuel cell, a typical cell phone battery could last more than 300 percent longer than with a traditional battery extending standby time from four days to two weeks and talk time from six hours to two days. LLNL’s tiny fuel cell incorporates integrated microfluidic fuel distribution architecture within a miniature thin film fuel cell package. This feature enables the fuel cell to operate from highly concentrated methyl alcohol fuel mixtures supplied from a replaceable fuel cartridge.
