Summary on Grant Application Form |
|
The proposed research programme is to exploit the use of Combustion Chemical Vapour Deposition (CCVD) as a novel processing technique which offers a simple and cost effective method to manufacture multilayer ceramic thick films of solid oxide cell components in one production process. The present proposal is principally concerned with strategic investigations based on the development of planar supported thick film electrolyte (STFE) configurations. Such STFE uses Zr(Y)02-x electrolytes for operation with methane fuel in the temperature range 650-800C. The aims of the present application are to develop a fundamental understanding of the processing variables and to optimise them so that high quality La(Sr)Mn03/Zr(Y)02-x/Ni-Zr02 multilayer PEN structures, can be fabricated on bi-polar ferritic stainless steel plate materials, and porous substrates. Optimisation of processing parameters including deposition temperature, precursor composition, size of spray droplet and spray rate will be performed in order to control density, porosity, grain size composition of each layer and interfaces between layers in the PEN structure. Characterisation of the individual thick films and the PEN assembly will include microstructural examination, together with electrical measurement and mechanical testing. Prototype PEN cells will be fabricated using CCVD. The electrochemical performance of cells will be evaluated in collaboration with Rolls-Royce and British Gas.
