Brief description

New approach for design and modification of metal oxide porous nanosize particles able to polarization plenties of water molecules and method of doping of the Nafion membrane for giving of new properties toward development of performance and compactness high temperature fuel cell.

Expected results

The project is targeted on the development of the design and modification of the metal(Si, Ti) oxide nanocomposites various morphology able to polarization plenties of water molecules wherein swelling Nafion structure with the aim to provide the water management and their reliable operation at temperature > 100°C and to strengthen the mechanical stability the membrane.

Advantages

Fulfillment of the project can leads to improvement of performance and water management of polymer electrolyte composite membrane fuel cell at temperature >100°C, improve, on higher level of existed, increase of mechanical stability of the Nafion membrane. The results of project can be also used under development of of more compact fuel cells based on polymer membrane.
