Enhancing solid oxide fuel cells with nanoscale thin film surface modification

Abstract

This final year project explores the application of Atomic Layer Deposition (ALD) for precise surface modification of SOFC electrodes. The research aims to improve the efficiency and functionality of these electrodes in clean energy technologies.

The project investigates the use of ALD to deposit ultrathin films of various materials on electrode surfaces. By precisely controlling the deposition process at the atomic level, the project seeks to optimize the interaction between the electrode and air. The methodology involves fabricating and characterizing modified electrodes using ALD techniques. In this project, we will be fabricating SFMO-LSGM electrodes and coating it with metal oxides, specifically Zirconia (ZrO2) and Hafnium Oxide (HfO2). Electrochemical performance will be evaluated to determine the impact of different thin film materials on the long-term durability.

This research is expected to reveal key insights into how nanoscale surface modifications with ALD can enhance the electrode performance in air. The findings can pave the way for the development of more efficient and durable electrodes for applications in solid oxide fuel cells.
