Copper promises cheaper, sturdier fuel cells
November 22, 2013
Duke University chemists are exploring the use of copper nanowires in fuel cells to convert solar energy into storable fuel. Copper nanowire catalysts cost less to produce than their indium tin oxide counterparts because they can be "printed" on pieces of glass or plastic in a liquid ink form, using a machine that functions much like a printing press. The nanowires can also be incorporated into transparent, flexible films.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2015, its budget is $7.3 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 48,000 competitive proposals for funding, and makes about 11,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
