Objective It is proposed to develop a high temperature water electrolyser with very high electrical efficiencies. The Hot Elly project has demonstrated that a breakthrough in water electrolysis efficiencies is possible by going to high temperatures (900-1000°C). The electrical efficiencies demonstrated in the Hot Elly electrolyser was close to 92% compared to 50-60% in traditional alkaline electrolysers. By making use of an external source of heat such as concentrated solar, it is possible to increase the electrical efficiency even further.The project aims to make use of the materials and technological developments that have been made in the last 10 years on planar SOFC technology and to apply to develop and evaluate a planar Solide Oxide Water Electrolyser (SOWE). Two different technologies will be developed using the SOFC cells as a starting point: anode supported cells and metal supported cells. The degradation of the SOWE will be analysed and the main mechanisms identified. Improved metal alloys and coatings as well as anode and cathode materials will be developed to limit any corrosion. The objective the project will be to demonstrate a degradation inferior to 1%/1000 hours on a short 5x5 cm2 stack for a period of 2000 hours.
