Abstract

The results of the manufacture and research of metal-supported solid oxide fuel cells are presented. As a metal support the porous Ni-Al plates manufactured by self-propagating high temperature synthesis were used. The effect of synthesis conditions and composition of green mixture on the phase composition, microstructure, porosity, gas permeability and other properties of the Ni-Al samples were investigated. Solid oxide fuel cells with the structure of “Ni-ZrO₂:Y₂O₃ anode” / “ZrO₂:Y₂O₃ electrolyte” / “La_0.8Mn_0.2SrO₃ cathode” were formed on the surface of porous Ni-Al supports by the methods of high-temperature sintering and magnetron sputtering. Power density of a fuel cell on a metallic support reaches 400 mW/cm² at 800°C when humid H₂ was used as fuel and air was used as an oxidant.
