Ni-based Alloys as Protective Layer for a Conventional Solid Oxide Fuel Cell Fed with Biofuels
Bimetallic Ni-based alloys mixed with gadolinium-doped ceria in order to obtain a composite material with mixed electronic-ionic conductivity utilized as a barrier layer in a conventional anode-supported solid oxide fuel cell may represent a practical solution to provide a mitigation of the degradation reactions occurring during the feeding of biofuels.
In this communication, we report few guidelines for the preparation of catalysts having proper behaviour for the utilization as protective layer. Complete physico-chemical characterization and electrochemical investigation of Ni0.5M0.5(M=Cu, Co, Sn, Zn, Fe) will be discussed.
