Abstract

The invention discloses a low-temperature solid oxide fuel cell based on zinc oxide-sn2 oxide composite material, the cathode and the anode of the fuel cell are nickel foam coated with NCAL on the surface, and the electrolyte layer of the fuel cell is SnO / ZnO / NCAL Composite. That is, the structure of the fuel cell of the present invention is: nickel foam / / NCAL / / SnO / ZnO / NCAL / / NCAL / / nickel foam. The low-temperature solid oxide fuel cell of the present invention uses nickel-cobalt-aluminum-lithium and wet-synthesized SnO / ZnO composite materials as the electrolyte layer of the oxide fuel cell, which greatly reduces the electrode polarization loss during the electrochemical reaction process of the fuel cell; The electrolyte material has good output power in the low temperature section, 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 invention relates to a low-temperature solid oxide fuel cell based on zinc oxide-tin oxide composite material, which belongs to the technical field of new energy. Background technique [0002] Solid oxide fuel cells can efficiently convert chemical energy in fuel (such as hydrogen, methane, etc.) into electrical energy. The conversion efficiency is not limited by the Carnot cycle, and its efficiency is much higher than that of thermal power generating units. Fuel cells can be divided into proton exchange membrane fuel cells, solid oxide fuel cells, alkaline fuel cells, molten carbonate fuel cells, and phosphate fuel cells according to their electrolyte classification. Among them, solid oxide fuel does not require noble metal catalysts, materials The advantages of wide selection range and high conversion efficiency have attracted widespread attention. However, the current solid oxide fuel cells mainly use yttria-stabilized zirconia (YSZ) as the el...
