Abstract
A monolithic solid oxide fuel cell of the type characterized by a plurality of fuel and oxidant passageways extending through the core of the fuel cell. The fuel cell is constructed only of anode, cathode, electrolyte and interconnect materials and is formed with integral manifolding for parallel flow through the core. The cell is constructed using alternatively stacked electrolyte walls and interconnect walls which are themselves multilayer tapes formed by roll milling individual tapes of a desired material, and then roll milling the multilayer tape from the tapes of a single material. A manufacturing process is also disclosed.
