Chipmaker STMicroelectronics is joining in the race to develop fuel cells for portable equipment. Its Geneva, Switzerland research center has developed a 3D technique for making the membranes found in fuel cells. Using nanoporous layers made from silicon provides millions of pores that measure only a few nanometers in diameter, yielding more surface area for chemical reactions to take place. The company did not estimate a timeframe for commercialization.
