Japan-based Seiko Instruments hopes to launch its small polymer electrolyte fuel cell (PEFC), which stores and produces hydrogen using sodium borohydride, in 2009. 

The International Civil Aviation Organization announced it would permit sodium borohydride-based micro fuel-cell cartridges to be used on electronic devices beginning Jan 2009. 

Seiko will determine by the end of Feb 2008 the specifications and composition of the fuel cell, including stainless steel for the separators and fluororesin for the electrolyte membrane. 

A prototype of the PEFC was produced by Seiko in 2007 in a stack of 10 cells. 

With overall dimensions of 210 mm by 120 mm by 170 mm, the prototype attained 50 watts power output and 16 volts output voltage.
