Pollutant nitrogen oxides and particulate matter are captured at the electrodes of the cell, which uses the porous solid electrolyte already used in solid-oxide fuel cells.

Decomposition rates of more than 90% have been achieved when a low current is passed between the electrodes. 

The cell can be made from low-cost ceramics and a platinum catalyst is not required. 

Potential applications include treatment of exhaust gases from diesel-powered vehicles and the use in industrial furnaces. 

A partner is being sought with a view to commercializing the technology in FY2011 (starting Apr 2011). 

The cells could replace existing technology which reduces the fuel efficiency of diesel engines.
