Ni- and Ni-Sn Anode Porous Layers for SOFCs Operating with Carbonaceous Fuels

Nickel metal layers with various morphologies have been investigated as electrical contact, electrocatalyst, and catalyst layers for high temperature hydrogen electro-oxidation and heterogeneous reactions, such as steam methane reforming and water gas shift, in high temperature fuel cells supplied by carbonaceous fuels of various nature. Ni metal alloys, with various dopant concentrations, have been studied to increase metal nickel tolerance to carbon deposition, which is thermodynamically favored in SOFC fed with a steam/methane molar ratio
