Development of low temperature cost effective solid oxide fuel cells (SOFCSPRAY)


Solid Oxide Fuel Cells (SOFC) enabling the direct conversion of the chemical energy of hydrocarbons into electricity are drawing much and increasing interest as a power generation system. They possess high power generation efficiency (up to 70 %), which is the highest conversion efficiency compared with any of the developed fuel cells (PEMFC, MCFC etc.). SOFC could be used today in big, high power applications including industrial and large-scale central electricity generation stations. Some developers also see SOFC use in motor vehicles and are developing fuel cell auxiliary power units. The main objectives of the project are to reduce the working temperatures of planar SOFC from 1000 800 DC to 650-700 DC and their manufacturing costs by 50 % by usi ng new powders and advanced thermal spraying techniques. In order to achieve these objectives new powders to be used for the development of the materials for the fuel cell elements will be developed. For the manufacturing ofSOFC high velocity oxy-fuel (hvOF) spraying and a novel technology of the microplasma spraying (MPS) will be used. These two spray techniques have not-been used so far for design and development of the SOFC elements. They would enable the manufacturing of low temperature and cost effective SOFC. Characterization and optimization of the developed powders will be provided to meet the requirements and specifications of industrial partners. The structure and properties of the elements of SOFC (anode, cathode and electrolyte) develope d by thermal spraying using these powders will be evaluated in order to establish the optimum structure-properties relationships. The SOFC elements will be assembled in a stack which will be tested under the industrial conditions taken into account the industrial specifications.
