摘要：

Some high-temperature alloys have been investigated in order to determine whether they are suitable as metallic interconnect materials in solid oxide fuel cell stacks. The requirements for such alloys are formulated. Thermal dilatometry and oxidation tests, as well as theoretical calculations of the stresses that are induced by differences in thermal expansion of the individual materials, have been performed. The results show that a chromium-rich alloy, with dispersions of fine Y2O3 particles, perform best among the samples investigated. Improvements are still needed in order to make the alloy fully applicable in a solid oxide fuel cell stack. Some suggestions for improvements are put forward.
