简介 PROBLEM TO BE SOLVED : To provide oxidation-resistant ferritic steel alloys for separators for solid oxide fuel cells and the other applications requiring high temperature stability and oxidation resistance. SOLUTION : Oxidation-resistant ferritic steel alloys has a composition consisting essentially of chromium (Cr) in an amount from 18 to 25 atom%, tungsten (W) in an amount from 0.5 to 2 atom%, manganese (Mn) in an amount less than 0.8 atom%, aluminum (Al) in an amount less than 0.2 atom%, silicon (Si) in an amount less than 0.1 atom%, and rare earth metals that include neodymium (Nd) in an amount from 0.002 to 0.2 atom% with the balance being iron (Fe). Also disclosed herein are solid oxide fuel cells 10 that include separators 20 formed from the oxidation resistant ferritic steel alloys. COPYRIGHT : (C)2008, JPO&INPIT
