The present invention discloses manufacturing of a single component electrolyte-separation-membrane-free fuel cell by using a commercial cobalt-nickel-lithium oxide and cerium oxide-doped composite material. According to the present invention, the single component material is a two-phase composite material and is prepared by a dry method and a wet method, wherein the dry method comprises 1, preparing an ion cerium oxide-doped material and 2, further mixing with a commercial cobalt-nickel-lithium oxide according to different weight ratios to obtain the finished product, and the wet method comprises 1, preparing an ion cerium oxide-doped solution, and further adding 1-95% of a commercial cobalt-nickel-lithium oxide and a cross-linking agent, 2, heating to achieve a gel-dry gel state, and 3, calcining for 1-10 h at a temperature of 500-800 DEG C to form the single component material. According to the present invention, the composite material of the present invention is assembled into the single component electrolyte-separation-membrane-free fuel cell, and the power density of 100-510 mW/cm can be output at a temperature of 300-550 DEG C; the cheap cobalt-nickel-lithium oxide is adopted as the raw material, such that the solid oxide fuel cell has characteristics of low cost and low working temperature; and the use effect is good, and the method is suitable for mass promotion application.
