Abstract: The invention relates to solid oxide fuel cell anodes, in particular anodes which containing porous particles coated with catalytic nickel. The use of porous particles as a carrier for the nickel catalyst helps to overcome some of the redox stability issues experienced by some systems and improves the internal reforming properties of the system and permits less nickel to be used in SOFC systems.
