Abstract

A solid oxide fuel cell generator (10) is made which contains a plurality of bundles (14) of solid oxide fuel cells (36), the fuel cells, capable of generating electrical current, a bus bar unit (128) in adjacent contact with the plurality of fuel cell bundles at the sides of the generator, where the bus bar unit (128) can pass electrical current from the adjacent fuel cell bundles, the bus bar unit (128) containing inner flat plate/screen sections (130) near the fuel cell bundles, outer solid nickel bar (134) and with wide, solid, flexible, corrugated nickel strap electric current take-off connections (136) between the screens and bar; a power lead (140) electrically connected to the outer solid nickel bar, and also electrically through the bus bar unit to the fuel cell bundles through the take-off connections and inner screen sections; where the inner screen sections (130) and take-off connections (136) pass electrical current generated in the fuel cell bundles through the bus bar units (128) to an electricity receiving source.
