SIDE - LEAD INTERCONNECTION FOR ALLOY - SEPARATOR PLANAR STACKS

摘要

A new idea of flexible interconnections between air electrodes and alloy separators in planar stacks is presented. The edge of the air electrode support of a cell is connected with a LaCrO_3 ring which is sandwiched with the edges of adjacent alloy separators. The electric current in the cell flows radially in the LSM support and collected to the LaCrO_3 ring. The LaCrO_3 ring is connected to the alloy separator with a nickel felt in the fuel gas atmosphere. By using the proposed interconnections, we can avoid the difficulties in the junctions between air electrodes and alloy separators in conventional planar stacks.
