Abstract

The invention discloses a low-temperature solid oxide fuel cell based on calcium stannate / strontium-iron-molybdenum composite material. The cathode and anode of the fuel cell are nickel foam coated with NCAL on the surface, and the electrolyte layer of the fuel cell is CSO / SFM composite material. That is, the structure of the fuel cell of the present invention is: nickel foam / / NCAL / / CSO / SFM / / NCAL / / nickel foam. The low-temperature solid oxide fuel cell of the present invention adopts the composite material of calcium stannate and strontium-iron-molybdenum of perovskite structure as its electrolyte layer, which greatly reduces the electrode polarization loss in the electrochemical reaction process of the fuel cell; The low temperature section has good output power, so that the solid oxide fuel cell using the electrolyte material can operate efficiently and stably for a long time in the low temperature section (300-600 degrees).

Description

Technical field [0001] The present invention relates to a low temperature solid oxide fuel cell based on a tinate / ruthenium lybore composite, which belongs to the new energy technology. Background technique [0002] Solid oxide fuel cells can convert chemical energy in fuel (such as hydrogen, methane, etc.) into electrical energy. The conversion efficiency is not limited by the Carno cycle, its efficiency is much higher than the fire generator set. The fuel cell can be divided into proton exchange membrane fuel cells, solid oxide fuel cells, alkaline fuel cells, molten carbonate fuel cells, phosphate fuel cells, and solid oxide fuels, material, material, material. The advantages of wide selection and high conversion efficiency are widely concerned. However, the current solid oxide fuel cell mainly uses cerium oxide stabilized zirconia (YSZ) as an electrolyte, and YSZ needs to achieve high catalytic activity at high temperatures (900 degrees). Therefore, conventional solid oxide...
