They could even serve as self-cleaning coatings, because of their highly hydrophobic properties.

Dane Morgan and Ph.D. student Edward (Ted) Holby, from the University of Wisconsin-Madison have discovered that making the fuel cells from very small platinum nanoparticles decreases their lifetime. Making them bigger is, though, better.
