Nokia, historically one of the strongest proponents of fuel cells, is shelving their efforts for now:
http://news.bbc.co.uk/2/hi/science/nature/4318925.stmFrom today's BBC News article:
Mobile giant Nokia has dropped plans to develop mobile phones with fuel cells for at least the next few years.
The firm committed to fuel cells eight months ago but has now said the sector is "not yet mature".
Nokia's Matti Naskali said the firm had not abandoned the technology, saying: "Fuel-cell technology is promising and Nokia continues to follow it closely."
