The Monolithic Solid Oxide Fuel Cell (MSOFC) under development at Argonne National Laboratory is an oxide-ceramic structure in which appropriate electronic and ionic conductors are fabricated in a ''honeycomb'' shape similar to a block of corrugated paperboard. The electrolyte conducts oxygen ions from the air side to the fuel side and is made from yttria-stabilized zirconia (YSZ). All the other materials are electronic conductors, including the nickel-YSZ anode, the strontium-doped lanthanum manganite cathode, and the doped lanthanum chromite interconnect (bipolar plate). These electronic and ionic conductors are arranged so that they provide short conduction paths to minimize resistive losses. The power density achievable with the MSOFC is expected to be 8 kW/kg or about 4 kW/L because of the small cell size and low resistive loses in the materials. The MSOFC operates in the range of 700 to 1000/degree/C, at which temperatures rapid reform of hydrocarbon fuels is expected within the nickel-YSZ fuel channels. 3 refs., 4 figs.
