Abstract

An electrochemical cell comprises a first electrode, a second electrode, and a proton-conducting membrane between the first electrode and the second electrode. The first electrode comprises a layered perovskite having the general formula: DAB2O5+δ, wherein D consists of two or more lanthanide elements; A consists of one or more of Sr and Ba; B consists of one or more of Co, Fe, Ni, Cu, Zn, Mn, Cr, and Nd; and δ is an oxygen deficit. The second electrode comprises a cermet material including at least one metal and at least one perovskite. Related structures, apparatuses, systems, and methods are also described.
