COMPOSITE ELECTRODE MATERIAL FOR ELECTROCHEMICAL DEVICES Russian patent published in 2014 - IPC H01M4/48 H01M8/10 H01M8/12 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of catalysis, namely to catalytic active porous composite materials, which can be used as carrying electrodes of electrochemical devices for obtaining hydrogen and/or oxygen or high- and medium-temperature solid oxide fuel elements (SOFE). The invention relates to a composite electrode material for electrochemical devices, which contains a metal component in the form of a two-component alloy of nickel with aluminium and a ceramic oxide component; as the two-component alloy used is aluminium-plated nickel, with aluminium content of 3-15 wt %, and as oxide component used is aluminium oxide. The material composition is characterised by a weigh ratio of the metal component to the oxide component in accordance with formula yNi_xAl_100-x-(100-y)Al₂O₃, where x=85÷97; y=30÷60.

EFFECT: obtaining a porous carrying electrode for electrochemical devices with improved thermodynamic stability, catalytic activity, high electric characteristics.
