The successful implementation of PlaNet demands the development and optimization of novel materials and the integration and combination of several methodologies and physicochemical and electrochemical methods, as well as engineering aspects and technical substantiation. The technical goals of the project are:
I. Development of a hybrid polymer/inorganic electrolyte membrane based on perfluorosulfonic acid ionomers (Nafion type) and self-assembled nanoadditives, significantly thinner and mechanically reinforced due to the formation of the inorganic network, highly efficient and stable. The new materials must: → Eliminate polymer deterioration due to anodic electrocatalytic oxidation and → Provide low specific resistance of the electrolyte and minimal gas crossover.
II. Optimization of both cold plasma reactor configuration and operational parameters ensuring the proper modification of the inorganic nanoadditive surface that will lead to the aforementioned network.
III. Compatible and efficient membrane/electrode assemblies using the optimized electrolytes and home-made electrocatalysts. Understanding the operational/ degradation processes through in-situ electrochemical characterization.
