DIFFUSION STABILIZED GAS BARRIERS |
摘要 |
A metallic barrier ( 1 ) and a method for separating fuel ( 5 ) and oxidant ( 6 ) gases are disclosed for use in high temperature systems such as solid oxide fuel cells (SOFC) or cell stacks. The metallic barrier ( 1 ) can be formed as a metallic bipolar separator plate or a seal, without requiring the use of chromium alloys or noble metals. Controlled diffusion of fuel gas ( 5 ) through the metallic barrier ( 1 ) limits the thickness of an adherent electronically insulating oxide layer ( 4 ) on an opposing surface in contact with oxidant gas ( 6 ). This stabilized oxide layer may be penetrated by refractory conductive particles such as doped lanthanum chromite to provide multiple electronically conductive paths through the oxide layer and the metallic barrier. |
