  • Method of fabricating a monolithic solid oxide fuel cell
    Patent number: 5290642
    Abstract: In a two-step densifying process of making a monolithic solid oxide fuel cell, a limited number of anode-electrolyte-cathode cells separated by an interconnect layer are formed and partially densified. Subsequently, the partially densified cells are stacked and further densified to form a monolithic array.
