Summary on Grant Application Form
Internal steam reforming of natural gas fuel within a Slid Oxide Fuel Cell stack is very attractive because it removes the requirement for a separate external reformer. Unfortunately the rapid endothermic reforming reaction causes a severe thermal shock that will fracture the ceramic electrolyte even if the reforming is not carried out indirectly within the cell anodes. This problem can be overcome if the reforming is slowed down and carried out indirectly within the fuel channels of the stack. The aim of this project is to configure a steam reforming catalyst with the appropriate mass and heat transfer characteristics to achieve this. In order to maintain stability and resistance to poisoning over long periods of operation the catalyst cannot simply be a diluted version of a conventional catalyst. In this project the use of additional mass transport barriers will be investigated to slow down the reforming rate together with novel oxide catalysts of lower intrinsic activity. The catalyst behavior will be modeled, combining the interacting effects of local reaction rate and heat and mass transport in the composite catalyst particles. The model will be used to design appropriate catalysts whose performances will then be verified on the laboratory scale.
