| 摘要 |
The invention relates to an oxide material of general formula (I) A2-x-yA' XA " yM1-z M' Z04+<,wherein A and A' are independently a metal cation of a group formed by lanthanides and/or alkalis and/or alkaline earths, A'' is a cationic gap, i.e. a cation vacancy A and/or A', M and M' are independently a metal of a group formed by transition metals such as 0<y<0.30, preferably 0 < y = 0.20; 0 < delta< 0.25, preferably 0 < delta < 0.10; 0 = x = 1; and 0 = z = 1. An air electrode containing said material and an electric power producing device in the form of a fuel cell provided with at least one electrochemical cell comprising said electrode are also disclosed. |
