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.

Abstract

The invention discloses a low-temperature solid oxide fuel cell based on a composite material. The electrolyte layer of the fuel cell is a stannous oxide composite material doped with cerium; the cathode and the anode of the fuel cell are coated with NCAL nickel foam. The low-temperature solid oxide fuel cell of the present invention adopts a one-step chemical wet method to prepare a cerium-doped stannous oxide composite electrolyte material, and the obtained cerium-doped stannous oxide composite electrolyte material can prevent electron transmission, At the same time, the transmission speed of oxygen ions is enhanced, so the composite material has good output power in the low temperature section, and the tin oxide composite electrolyte material doped with cerium can also reduce the electrode polarization loss during the electrochemical reaction of the fuel cell; Therefore, the solid oxide fuel cell using the electrolyte material can operate efficiently and stably for a long time at a low temperature range (300-600 degrees).

Description

technical field [0001] The invention relates to a composite material-based low-temperature solid oxide fuel cell, which belongs to the technical field of new energy sources. 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 electrolyte, and Y...
