Embodiment Construction

[0030] The present invention can be better understood from the following examples. However, those skilled in the art can easily understand that the content described in the embodiments is only for illustrating the present invention, and should not and will not limit the present invention described in the claims.

[0031] Such as figure 1 As shown, the nickel foam that the surface is coated with NCAL constitutes a symmetrical electrode, the fuel cell cathode and anode of the present invention all adopt the nickel foam that the surface is coated with NCAL, and the core electrolyte layer is NNO and SCDC composite material, so the structure of the fuel cell is: foam Nickel / / NCAL / / NNO / SCDC / / NCAL / / Nickel Foam; Among them, NCAL is Ni 0.8 co 0.15 al 0.05 LiO 2-δ Material, SCDC is the Ca prepared by the present invention 0.04 SM 0.16 Ce 0.8 o 2-δ material or the SCDC prepared by the existing disclosed method; NNO is the NdNiO prepared by the present invention 3 material or NNO p...

Abstract

The invention discloses an oxide fuel cell based on a neodymium nickelate and samarium-calcium co-doped cerium oxide composite material. A cathode and an anode of the fuel cell are foamed nickel withNCAL coated on the surfaces, and an electrolyte layer of the fuel cell is an NNO/SCDC composite material. The structure of the fuel cell is foamed nickel//NCAL/NNO/SCDC//NCAL/foamed nickel. Neodymiumnickelate which is of a perovskite structure and a samarium-calcium co-doped cerium oxide composite material are used as the electrolyte layer, so that the electrode polarization loss in the electrochemical reaction process of the fuel cell is greatly reduced; In addition, the electrolyte material has good output power in a low-temperature section, so that the solid oxide fuel cell adopting the electrolyte material can efficiently and stably operate for a long time in the low-temperature section (400-600 DEG C).

Description

technical field [0001] The invention relates to an oxide fuel cell based on the co-doped cerium oxide composite material of neodymium nickelate and samarium calcium, 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-stabili...
