Novel Cold-Plasma Induced Inorganic Network Formation in Nanohybrid Polymer Electrolytes for Water Splitting
Start Date: 01/07/2021,     End Date: 30/06/2023

PlaNet focuses on a key core component of the electrolysis cell, the electrolyte, and proposes a new approach to develop a reinforced nanostructured organic/inorganic hybrid polymer electrolyte comprising a typical sulfonated tetrafluoroethylene structure (Nafion type) and self-assembled inorganic nanomaterials, optimizing its performance and stability. Such an approach understands the various critical still unsolved issues concerning the current technology and aims at further progress by going beyond simple dispersion of the inorganic and aiming at the reinforcement of the polymer, as a result of a percolated inorganic network inside its structure to withstand the most challenging and corrosive environment of an electrolytic cell.

The technical goals of the project are:

  1. The 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.
  2. The optimization of both Cold-Plasma (CP) reactor configuration and operational parameters ensuring the proper modification of the inorganic nanoadditive surface.
  3. The preparation of compatible and efficient membrane/electrode assemblies produced from the optimized electrolytes and home-made electrocatalysts. Understanding the operational and degradation processes through in-situ electrochemical characterization.
