PolyFuel plans to announce that it has achieved a breakthrough in fuel-cell membranes by using an alternative material: a hydrocarbon that it says costs only about half as much per square meter as the conventional material. Compared with the fluorine compounds that are the most commonly used for membranes in fuel cells now under testing, PolyFuel says that hydrocarbon membranes allow production of more electricity per square centimeter of membrane. That could mean that a fuel cell could produce the same power as a fluorine-membrane version, but would be smaller and lighter, according to the company. [ more ] PolyFuel is currently privately held.
