Abstract

Construction of an SOFC stack by connecting individual solid oxide fuel cells using a novel metallic interconnect plate, typically alloy UNS 544400, into which alloy tubes are brazed. As these tubes extend from the centre of the interconnect and pass through the hot zone walls, their ends are therefore at ambient temperatures allowing polymer tubing connections to reactant supplies. The alloy tubes also function to remove power from the stack, and, uniquely, allow faulty cells to be ‘shorted out' avoiding stack failure. The alloy tube to each anode can contain a porous bed of reforming agent to convert fuel gases to hydrogen and carbon monoxide for direct use by the cell. A novel fugitive pore former, combined with electrically conducting cement, joins the cells to the metallic interconnects, and functions to distribute the feed gases uniformly over the active cell surfaces.
