Top hydrogen-storing polymer revealed

A series of computer simulations has identified a polymer material with a very large capacity for storing hydrogen that could be exploited in fuel cells. Jisoon Ihm and colleagues at Seoul National University in South Korea have discovered that polyacetylene with titanium atoms attached to the polymer chain can hold 63 kilograms of hydrogen per cubic metre -- more than any other similar material in their survey.

The figure shows the atomic configuration of titanium-decorated cis-polyacetylene with five hydrogen molecules (in red) attached to each titanium atom (in blue). Polymer backbone atoms (carbon) are indicated in green (image courtesy: J Ihm).

Pronto, o hidrogênio já não é mais a coisa menos poluente que existe. Agora só vai dar gente jogando no lixo célula de titânio usada...
