Nanoparticle Catalysts Promise More Efficient Fuel Cells
Research conducted at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory which indicates a possible method for producing less costly and more efficient catalysts for improving the performance of fuel cells is to be presented at the 233rd National Meeting of the American Chemical Society. The X-ray studies show that copper can be substituted for gold in reactions that keep fuel cells functioning longer while eliminating unwanted byproducts.
The DOE's sponsorship of the research is motivated by its duty to ensure U.S. energy requirements can be met, and so researchers are focusing on potential applications for hydrogen, whish is envisioned as a leading fuel source of the future. With the goal of efficient fuel cell operation in mind, scientists aimed to find catalsyts that would overcome the technical obstacles and operational disadvantages that currently afflict fuel cell technologies.
