PROJECT SUMMARY: Air pollution is currently the most important environmental risk to human health, and it is perceived as the second biggest environmental concern at national and international level. In this context, the replacement of the energy from fossil fuels with clean/green energy sources is imperative and the use of Direct Methanol Fuel Cell represents a viable solution to pollution issues, being one of the best candidates for the next-generation power source. The scope of the project proposal is to overcome two of the technical issues concerning the DMFC performance by: (i) developing a new preparation method of CoPt nanoparticles in order to increase the catalysts activity and decrease the platinum content and (ii) increasing the catalyst stability by exploiting the unique properties of CNTs. Within the framework of this project, a complex experimental study on the preparation, characterization (dimensional, morphological, structural and magnetic) and testing of new CoPt/CNTs nanocomposite materials will be accomplished, in order to choose the adequate catalysts in terms of nanoparticles diameter, morphology, structure and composition. By fulfilling the project proposal activities, we will contribute to the improvement of DMFC performances and stability and we will develop the experimental research work in the field of preparation of new catalysts based on CoPt /CNTs nanocomposite, focused on practical and immediate applications to renewable energy sources and catalyst industry.

PROJECT OBJECTIVE: The main Objective of this project is to improve the performance and efficiency of the DMFC fuel cells by optimizing the electrode properties and stabilities that will yield the highest current and power densities.

EXPECTED RESULTS: Preparation of new catalysts based on CoPt /CNTs nanocomposites with high catalytic activity for methanol oxidation reaction (MOR) and high electrochemically active surface area, and high stability under operating conditions. The as-obtained composite materials will be used as catalysts for preparation of DMFC anodes and their stability and efficiency will be tested in fuel cells operating conditions and will be compared with widely used carbon black supports.
