Symmetrical electrode structure fuel cell prepared from nanocomposite material

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.
