Hitachi Metals, Ltd.

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 interconnector (separator) 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 problem for conventional heat-resistant alloys as follows;
(1) 430SS does not have sufficient oxidation resistance,
(2) austenitic alloys with good oxidation resistance 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.

We, Hitachi Metals, Ltd. , as being your beneficial supplier, always keep ZMG232L stock and Instant Delivery System mainly, for your “R&D”.
