NICKEL-ALUMINUM ALLOY FUEL ELECTRODE AND SIMPLIFIED PRODUCTION METHOD THEREOF TO IMPROVE CREEPAGE AND SINTERING RESISTANCE, ACTIVATE ELECTROCHEMICAL REACTION AND POROSITY OF THE ELECTRODE

摘要

PURPOSE: A nickel-aluminum alloy fuel electrode and simplified production method thereof are provided to: reduce the fraction rate of micropores which are not participated in the electrochemical reaction; improve the electrochemical reaction by filling lithium/sodium electrolytes into the electrode with a sufficient amount; reduce the thickness of the electrolytes, thereby helping to reduce the size of an initial fuel cell stack; and improve creepage and sintering resistance. CONSTITUTION: The nickel-aluminum alloy fuel electrode is produced by: mixing a nickel-aluminum alloy powder with a solvent; mixing the mixture with electrolytes and then ball milling them; defoaming the resulted nickel-aluminum slurry; carrying out tape casting of the defoamed slurry to obtain a green sheet; and carrying out continuous sintering of the green sheet.
