Abstract
A solid oxide fuel assembly is made, wherein rows (14, 24) of fuel cells (16, 18, 20, 26, 28, 30), each having an outer interconnection (36) and an outer electrode (32), are disposed next to each other with corrugated, electrically conducting expanded metal mesh (22) between each row of cells, the corrugated mesh (22) having top crown portions (40) and bottom shoulder portions (42), where the top crown portion (40) contacts outer interconnections (36) of the fuel cells (16, 18, 20) in a first row (14), and the bottom shoulder portions (42) contacts outer electrodes (32) of the fuel cells in a second row (24), said mesh electrically connecting each row of fuel cells, and where there are no metal felt connections between any fuel cells.
