Abstract
The invention provides a method for preparing a solid-state thin-film fuel cell. First, a first electrolyte layer is deposited on the outer peripheral surface of a first electrode by controlling a vacuum coating device, and the thickness of the first electrolyte layer is gradually reduced along a first direction. The direction is the same as the axial direction of the single-tube electrode; then control the vacuum coating equipment to deposit the second electrolyte layer on the outer peripheral surface of the first electrolyte layer, and make the thickness of the second electrolyte layer gradually increase along the first direction; then control the vacuum coating The device deposits a ring-shaped second electrode on the outer peripheral surface of the second electrolyte layer. The electrolyte layer of the solid-state thin-film fuel cell obtained by the preparation method includes two different electrolytes, wherein one electrolyte layer is bonded and matched with one electrode, and the other electrolyte layer is bonded and matched with the other electrode, so that the two electrolytes can be combined The advantage of making the battery can play the best battery performance.
Description
technical field [0001] The invention relates to the technical field of battery preparation, in particular to a preparation method of a solid thin film fuel cell. Background technique [0002] A fuel cell is a power generation device that uses the chemical reaction of hydrogen and oxygen to generate water to generate electricity. It is a battery with high energy conversion efficiency in the next generation of new energy solutions. Fuel (pure hydrogen or hydrocarbon gas) is fed into the anode of the fuel cell, and oxygen (or air) is fed into the cathode. In this way, the fuel at the anode is oxidized, the oxygen at the cathode is reduced, and electrons form an electric current through an external circuit, thereby continuously generating electricity. Because the entire chemical reaction process is a pure chemical reaction process of electron or ion exchange without combustion, the electrochemical reaction process of the fuel cell does not have to follow the Carnot cycle, resul...
