FUEL-CELL MODULE AND FUEL CELL Russian patent published in 2007 - IPC H01M8/12 H01M8/24 

FIELD: electrical engineering; module of solid oxide fuel cells.

SUBSTANCE: proposed solid-oxide fuel-cell module 30 has plurality of solid-oxide fuel cells 36, each of the latter incorporating first electrode 40, electrolyte 42, second electrode 44, and plurality of connectors 38 designed to electrically interconnect fuel cells 36 in series. First layer 40A is meant to optimize electrochemical activity of electrolyte 42 and second layer 40B, to ensure electron conductivity perpendicular to layers 40, 42, 44 of fuel cell 36; second layer 40B is disposed to ensure that its electron conductivity were different in different positions of layer. Second layer 40B, 44B has different composition or contacts first layer 40A, 44A through its cross-sectional area.

EFFECT: provision for uniform current collection from solid oxide fuel cells.
