Oxygen production apparatus using oxygen adsorbent containing Co and oxygen production method

摘要

PROBLEM TO BE SOLVED: To improve oxygen absorption ability and oxygen desorption ability by devising a value of x in the composition formula SrCoFeOwhich is an oxide of a perovskite structure.SOLUTION: An oxygen adsorbent comprises at least an oxide of a perovskite structure, the oxide represented by the composition formula SrCoFeO(where, 0.6≤x0.9, 0≤&sgr;≤0.5).
