Fuel Cells for stationary and cogenerative applications;
Aim of the project was the evaluation of different FC technologies for cogenerative applications through the simulation, theoretical study, design and systems demonstration as well as the development of new materials, components and prototypes.

In this context, CNR-ISTEC took part of the project activity “Development of materials and components for next generation FC for cogenerative applications”, developing and producing anion conducting Solid Oxide Fuel Cells with prototypal dimension (10 x 10 cm) as well as stainless steel-supported anodes for proton conducting FC.

Enabling technologies for the Electric System Research: components and materials;
Among the different goals of the project, ISTEC was involved in the project activity “Dense ceramic membranes for hydrogen purification”. Dense membrane technologies are able to selectively separate hydrogen with purity values higher than 99%, promoting the production of energetic vectors and fuels from renewable sources.

In this context CNR-ISTEC has developed all-ceramic mixed proton-electron conducting membranes with asymmetric architecture, operating in the 600-800°C temperatures range.

Electrochemical systems for energy production and storage;
The general aim of this project was:
• the optimization of electric storage systems currently available on the market but not yet competitive for ad-hoc applications (i.e. High temperature batteries, Lithium ion batteries, Vanadium Redox Flow Batteries);
• development of new technologies such as metal-air batteries and synthetic methane storage through CO2 and H2O electrolysis.

In this context, CNR-ISTEC was involved in the development and production of electrolytic ceramic Na-β alumina membranes for the production of planar NaNiCl prototypal batteries.
