METHOD OF CONSTRUCTING A MONOLITHIC FUEL CELL CORE OF A FUEL CELL FOR ELECTROCHEMICALLY COMBINING FUEL AND OXIDANT FOR GENERATION OF GALVANIC OUTPUT

摘要

A monolithic solid oxide fuel cell of the type having a plurality of fuel and oxidant passageways (20,26) extending through the core (14) of the fuel cell. The fuel cell is constructed only of anode (30), cathode (32), electrolyte (31) and interconnect (33) materials and is formed with integral manifolding (16,18) for parallel flow through the core. The cell is constructed using alternately stacked electrolyte walls (36) and interconnect walls (38) 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
