Alloy for SOFC Interconnector, ZMG™232L

Solid oxide fuel cell(SOFC) is a promising fuel cell with high efficiency operated at high temperatures in the range of about 600 to 1000 degrees C. Good properties are required for the separator(interconnector) material of SOFC as follows;

1. Good electrical conductivity at operating temperature,
2. Good oxidation resistance at operating temperature for a long time,
3. Coefficient of thermal expansion close to electrolyte material YSZ(zirconia ceramics).

There are some problems for conventional heat-resistant alloys as follows ;(1)430SS does not have sufficient oxidation resistance,(2)austenitic alloys with good oxidation resistance(ex.Inco600) have much higher thermal expansion than YSZ,(3)Al-containing ferritic alloys with better oxidation resistance than austenitic alloys have low electrical conductivity of oxide layer.

ZMG232L is a Fe-22%Cr ferritic alloy with a small addition of special elements for SOFC interconnector which is alloy-designed and developed to obtain these required properties at the same time. Oxidation resistance and electrical conductivity of ZMG232L are better than those of our conventional alloy, ZMG232.
