Problems solved by technology

If a semiconductor material is used as the electrolyte material of a fuel cell, it is easy to think of a short circuit phenomenon. Because of this, materials with semiconductor properties have not been used in fuel cells so far.

Embodiment Construction

[0028] 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.

[0029] like figure 1 As shown, the nickel foam coated with NCAL on the surface constitutes a symmetrical electrode, the fuel cell cathode and anode of the present invention all adopt the nickel foam coated with NCAL on the surface, and the core electrolyte layer is BSO and ZnO composite material, so the structure of the fuel cell is: foam Nickel / / NCAL / / BSO / ZnO / / NCAL / / Nickel Foam; Among them, NCAL is Ni 0.8 co 0.15 Al 0.05 LiO 2-δ Materials (can be purchased or prepared by a disclosed method), BSO is commercially available or prepared by the method of the present invention, ZnO is commercially available; foamed nickel is a commercially purchased foamed nickel mate...

Abstract

The invention discloses a low-temperature solid oxide fuel cell based on barium stannate / zinc 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 BSO / ZnO composite Material. That is, the structure of the fuel cell of the present invention is: nickel foam / / NCAL / / BSO / ZnO / / NCAL / / nickel foam. The low-temperature solid oxide fuel cell of the present invention adopts the composite material of perovskite structure barium stannate and nano-zinc oxide as its electrolyte layer, which greatly reduces the electrode polarization loss in the electrochemical reaction process of the fuel cell; in addition, the electrolyte material It 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 barium stannate / zinc 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 ...
