Abstract

The invention discloses a symmetrical electrode structure fuel cell prepared from a nanocomposite material. The prepared novel electrolyte material is composed of a samarium-doped cerium oxide-carbonate composite material, and the chemical expression of the material is Ce0.8Sm0.2O1.9-Na2CO3. The solid oxide fuel cell of a symmetrical electrode structure is prepared based on the novel electrolyte material, and an anode and a cathode of the cell are in a symmetrical form. Experiments indicate that the symmetrical electrode structure fuel cell is of full symmetry in structure, and the symmetrical form of the anode and the cathode on two sides of the electrolyte can also be realized in practical application. Experimental results indicate that the electrochemical performance of the symmetrical electrode structure fuel cell prepared from the nanocomposite material disclosed by the invention can be comparable with the performance of a traditional solid oxide fuel cell. Moreover, through the material and structural innovation, the operating temperature of the fuel cell is reduced, so that the technological requirements of sealing are reduced, and the fuel cell has market-oriented prospects.

Description

technical field [0001] The invention relates to a preparation method of a solid oxide fuel cell, in particular to a solid oxide fuel cell with a symmetrical electrode structure prepared from a nanocomposite material. Background technique [0002] Energy crisis and ecological environment are two major challenges facing mankind at present. Traditional coal, oil, etc. have been difficult to meet the strategic requirements of sustainable energy development. In the long run, renewable energy will become the main energy source for human beings in the future. Solar energy, as a clean, pollution-free and easy-to-obtain renewable energy, has become one of the most important renewable energy sources and has broad application prospects. Solid oxide fuel cell is a kind of direct conversion of chemical energy of hydrogen, methanol and other substances into electrical energy, which has significant advantages such as high energy conversion efficiency and no pollution. At present, there ...
