Abstract:
1. A fuel cell unit, comprising: a. an array of solid oxide fuel cell tubes, each of said tubes having a porous metallic support structure with porous metallic exterior surfaces and porous metallic interior surfaces, a porous first electrode layer radially inside and coated on said porous metallic interior surfaces, a dense electrolyte layer radially inside and coated on said porous first electrode layer, and a porous second electride layer radially inside and coated on said dense electrolyte layer, said porous second electrode layer having an interior electrode surface; b. at least one header in operable communication with said array of solid oxide fuel cell tubes, said header including structure for directing a first reactive gas into contact with said porous metallic exterior surfaces and structure for directing a second reactive gas into contact with said interior electrode surfaces, said header further comprising at least one busbar selected from the group consisting of an exterior busbar disposed in electrical contact with each of said porous metallic exterior surfaces and an interior busbar disposed in electrical contact with each of said interior electrode surfaces.
