Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
New membrane-electrodes assemblies with less platinum content can slash the costs of automotive fuel cells (FCs). An EU-funded project is developing a new electrode concept without compromising on FC efficiency and durability.
