are cooking up ways to make the alternative energy source more durable
and even cheaper. By combining graphene
-- think pencil lead -- and indium tin oxide (ITO) nanoparticles, the
team produced a catalytic material that is both stronger and more
chemically active than the usual catalytic combo. Fuel cells typically
carbon or metal oxides, to break down oxygen and hydrogen gases,
creating water in the process -- thing is, carbon is easily eroded by
the resulting water, and metal oxides, while more stable, are less
conductive. Using graphene -- which because of its porousness erodes
less quickly -- in combination with the stable ITO and platinum
nanoparticles, researchers have created what could be referred to as a
super fuel cell -- a stronger, longer lasting, and potentially cheaper
version of the alternative energy source. Unfortunately, without enough hydrogen filling stations, these super fuel cells won't come to anyone's rescue anytime soon.
