Japan Develops High - Active Catalyst To Promote The Popularity Of Fuel Cell

- Dec 28, 2017-

According to the website of ministry of science and technology, many inorganic metal oxides can be used as oxygen reduction, oxygen and hydrogen evolution reaction in the catalyst of energy conversion, but in most cases, their catalytic performance is not high.The main reason is that they have low conductivity and small catalytic activity.

Kyushu university in Japan has a good team with electrical conductivity of carbon nanotube (CNT) as basic material, first in polybenzimidazole (PBI ) will the package cover, and then by solvent hot method, in which the synthetic spinel structure of inorganic metal oxides (NixCo3 - xO4).The fuel cell made from this method is very efficient in the oxygen reduction and oxygen reaction of the catalyst, and the catalyst has a strong endurance ability.Team will ever make a CNT/PBI company/Pt catalyst is applied to the metal materials, inorganic evenly coated on the conductivity of nanotubes inorganic metal oxides nanocrystalline spinel structure, thus improve the catalyst activity.

The results are published in the electronic edition of Scientific Reports.
