Abstract

The invention discloses a fabrication method of a power generation assembly for evaporative power generation. The assembly for evaporative power generation comprises a carrying sheet, a first electrode, a second electrode and a carbon material layer. The fabrication method comprises the following steps of firstly, fabricating two electrodes parallel to each other on a surface of an electrical insulation carrying sheet by a conductive material; secondly, connecting paste containing a carbon material between the first electrode and the second electrode in an overlap joint way by a printing mode; and finally, annealing the printed paste layer, and forming the carbon material layer between the two electrodes. According to the fabrication method provided by the invention, the carbon material layer is fabricated by paste printing and annealing, and the material and the fabrication method of the paste are improved; and in the power generation assembly obtained according to the fabrication method, the interaction effect among carbon particles is higher, the carbon material layer is more firm, the power generation assembly can stably work for an ultra-long time, and the problem of poor stability of an evaporative power generation device caused by easiness in damage of the carbon material layer in an existing evaporative power generation assembly is solved.

Description

technical field [0001] The invention belongs to the field of new energy power generation equipment, and more specifically relates to a preparation method of a power generation component for evaporative power generation. Background technique [0002] With the gradual reduction of fossil fuels, the energy crisis is intensifying, and the environmental problems caused by the burning of fossil fuels are becoming more and more prominent. Therefore, the development and utilization of renewable and clean energy have attracted great attention. A device that uses solution evaporation to generate electricity can convert environmental heat into electricity. This electricity generation method is a new type of clean energy generation. Although the power generation of this power generation device is very low at present, as a new type of power generation, evaporation power generation is still considered to be a promising way to generate clean energy. [0003] The patent application No. 201...
