摘要： A multi-stage arrangement for the electrolyte material in a SOFC electrochemical power system. Multiple stages may be arranged in series, and each stage contains electrolyte elements which are constructed of a different material from the elements in previous and subsequent stages. A fuel gas admitted to the power system flows serially through each stage and is then exhausted from the power system. Upstream stages contain electrolyte elements made from an electrolyte material having low ion conductivity and high resistance. Subsequent stages contain electrolytes having progressively higher conductivity and progressively lower resistance. The fuel exhaust from an upstream stage is fed to the next downstream stage until the gas is exhausted from the final stage in the power system. Each stage operates at a progressively lower temperature than the previous stage. In a three-stage embodiment, a first stage has ZrO.sub.2, electrolyte material, a second stage has CeO.sub.2, and a third stage has Bi.sub.2 O.sub.3. The multi-stage fuel cell arrangement leads to a higher total power output for the same initial mass flow rate of fuel gases though the fuel cells.

摘要： A module for an ion-conducting device includes a plurality of spaced-apart, solid state ion-conducting electrolyte elements arranged substantially radially around a central plenum. A plurality of longitudinal gas flow channels is sealed off from the central plenum by a plurality of seals, and extend longitudinally through the module in the spaces between every other adjacent pair of electrolyte elements. A plurality of transverse gas flow channels is in fluid communication with the central plenum, and extend generally radially outward from it through the spaces between every-other adjacent pair of electrolyte elements not constituting a longitudinal gas flow channel. Manifold plates having a plenum aperture and a plurality of gas apertures therein are disposed on either side of the radially arranged electrolyte elements, and sandwich the elements therebetween. A plurality of the modules may be juxtaposed in a modular assembly wherein the central plenums of adjacent modules are aligned and in register, and combine to form an extended central plenum, the transverse gas flow channels in each module extend generally radially from the extended central plenum, and the longitudinal gas flow channels of adjacent modules are aligned and in register and in fluid communication and form extended longitudinal gas flow channels.
