Synthesis and Investigation of Porous Ni-Al Substrates for Solid-Oxide Fuel Cells

摘要

Self-propagating high-temperature synthesis (SHS) is applied for the production of porous supporting Ni-Al bases of solid-oxide fuel cells. The effect of synthesis conditions and the composition of source powders on the phase composition, microstructure, gas permeability, corrosion resistance, and other properties of obtained Ni-Al samples is investigated. The possibility is shown for the formation of solid-oxide fuel cells (SOFCs) on the surface of porous Ni-Al plates. The cells have the structure Ni-ZrO_3:Y_2O_3 anode/ZrO_3:Y_2O_3 electrolyte/La_(0.8)Mn_(0.2)SrO_3 cathode and provide a specific power of 400 mW/cm~2 at a temperature of 800℃.
