Carbon nanotubes play a pivotal role in a three-company effort to create small-scale fuel cells for portable electronics. The project, which recently received $3.6 million in funding from the National Institute of Standards and Technology, looks to establish a low-cost manufacturable hydrogen fuel cell based on proton-exchange membranes, or PEMs. The work is being conducted by Carbon Nanotechnologies, Motorola Labs and Johnson Matthey Fuel Cells.
