S3: 15th international symposium on solid oxide fuel

Solid oxide fuel cells (SOFC) offer potential for clean and efficient power generation from a wide variety of fuels ranging from hydrocarbons to renewables and coal derived fuels. Advanced systems configurations are currently being developed for applications in centralized and distributed stationary generation using SOFCs. Considerable progress has been made in SOFC based systems for automotive auxiliary power generation as well as in man portable and unmanned operation. With demonstrated advantages of high electrical efficiency, lower emissions (greenhouse gas, SOx, NOx, VOC and particulate matters) and ease of products configurability, major focus of interest continues to be on systems research and development, products engineering, and cost effective manufacturing under the sponsorship of government agencies and private industries. Although significant progress has been made in the areas of cell and stack materials, component fabrication, stack and systems simulation and design, fuel processing, and systems operation on a wide variety of liquid and gaseous hydrocarbons, technology development continues towards the identification of bulk and interfacial modifications for performance enhancement, understanding of aging phenomena, accelerated testing, and minimization of degradation, as well as cost reduction at both materials and process levels. Significant challenges still exist in the areas of durability enhancement, stacking cells, fracture mechanics of ceramic components, thermal management, and BOP component development at both sub-kWe and large multi-kWe levels.

 

Electrochemical energy conversion in solid oxide cell is reversible allowing power generation and fuel production. An essential goal of the modern energy supply is the transition from fossil to renewable energy sources like wind and sun. A disadvantage of these sustainable sources is their fluctuating nature. This necessitates the development of appropriate technologies for the storage of excess energy. High-temperature electrolysis can solve this problem providing highest efficiency for generation of chemicals and products from excessive power. In electrolysis, the regenerative energy is directly converted into hydrogen, and/or a synthesis gas which can be further processed into any fuel. The production of methane, synthetic oils, or diesel, in particular, provides promising synergies. So, it will be possible to couple electricity grid, natural gas grid, and chemicals production. For this reason the research on solid oxide electrolysis is important an task which helps to understand the opportunities and limitations of this new technology for future energy systems.
