Abstract
Tubular solid oxide fuel cells are provided. In one embodiment, fluid flow channels are defined by a plurality of bridges between a core and an outer wall of an electrode support. In another embodiment, a fluid supply channel and fluid discharge channels of an electrode support are formed in a double-wall structure. Electric current distribution and gas distribution are facilitated in the solid oxide fuel cells.
