Abstract

The invention provides a semiconductor thin-film electrolyte fuel cell and a manufacturing method thereof. The semiconductor thin-film electrolyte fuel cell structurally comprises a cathode layer, anelectrolyte layer and an anode layer, wherein the material of the cathode layer is an ABO3-type perovskite oxide material or a layered lithium-containing oxide material or a composite material of theABO3-type perovskite oxide material or the layered lithium-containing oxide material and 0-50wt.% of doped cerium oxide; the material of the electrolyte layer is a binary oxide semiconductor material;and the material of the anode layer is a layered lithium-containing oxide material or a nickel and cobalt oxide material or a composite material of the layered lithium-containing oxide material or the nickel and cobalt oxide material and the 0-50wt.% of doped cerium oxide. The manufacturing method comprises the following manufacturing steps of pressing an anode ceramic plate and then preparing athin-film electrolyte layer at one side of the anode ceramic plate; and pressing a cathode ceramic plate, then pressing the cathode ceramic plate and the anode ceramic plate together through lamination of the electrolyte layer and carrying out high-temperature sintering to obtain a product. An electrolyte thin film is relatively small, adjustable and controllable in thickness; the electrolyte material is simple in composition, low in preparation temperature and low in cost; and the battery has the characteristic of low operating temperature.

Description

technical field [0001] The invention belongs to the field of solid oxide fuel cells, and in particular relates to a semiconductor thin film electrolyte fuel cell and a manufacturing method thereof. Background technique [0002] Solid oxide fuel cell is a clean energy conversion device with high conversion efficiency. The solid oxide fuel cell was invented in 1839 and has experienced a development history of more than 170 years. Traditional solid oxide fuel cells are mainly composed of three layers of materials: anode, electrolyte, and cathode. The electrolyte layer of its core component is mainly yttrium stabilized zirconia material. The material needs to obtain an ionic conductivity of 0.1 S / cm at a high temperature above 1000°C. Therefore, solid oxide fuel cells generally need to work at a higher operating temperature, however, various problems caused by high temperature arise from this. For example, the matching of thermal expansion coefficients of the anode, electrol...
