Abstract

The invention discloses a low-temperature solid oxide fuel cell based on cerium oxide / ferric oxide 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 CeO 2 / Fe 3 o 4 composite material. That is, the structure of the fuel cell of the present invention is: nickel foam / / NCAL / / CeO 2 / Fe 3 o 4 / / NCAL / / nickel foam. The low temperature solid oxide fuel cell of the present invention adopts CeO 2 / Fe 3 o 4 The nanocomposite material as its electrolyte layer greatly reduces the electrode polarization loss during the electrochemical reaction of the fuel cell; the electrolyte material has high oxygen ion conductivity at low temperature, so that the solid oxide fuel using the electrolyte material The battery can operate efficiently and stably for a long time in the low temperature range (300‑600 degrees).

Description

technical field [0001] The invention relates to a low-temperature solid oxide fuel cell based on cerium oxide / ferric 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 t...
