Abstract
Porous alloys are used as supporting structures in high temperature fuel cells. A novel
concept is to fabricate metal supported protonic conducting fuel cells working at 600°C. This fuel cell
type offers several advantages for using porous alloy substrate in comparison to an oxygen conducting
solid oxide fuel cell. In this work corrosion properties of a Fe22Cr0.4Mn alloy in porous form are
evaluated in humidified hydrogen at 600°C and a method to improve its corrosion resistance is
reported. Supports in the not modified state corrode rapidly by formation of dual phase oxides whereas
after the modification by preoxidation supports offer high corrosion resistance allowing construction of
fuel cells.
