ELECTRODE AND ELECTROCHEMICAL CELL

Abstract

The invention relates to an electrode for an electrochemical cell, the electrode comprising at least a first layer comprising a nickel source and a first electrode material comprising cerium oxide doped with composition Ce (1-x) Ln x O(2-0.5x-δ), where x is a doping level between 0.001 and 0.08, Ln is Gd or Sm, and δ is the degree of oxygen deficiency. Electrochemical cells comprising such electrodes and stacks of such electrochemical cells are also disclosed. The invention further proposes a method for manufacturing an electrode for an electrochemical cell comprising applying an electrode composition as defined above to a substrate and optionally drying and sintering the composition to produce the electrode.
