A salt solution-based performance-enhanced water voltaic power generator comprises a functional film (1) having a conductive nanomaterial layer and electrodes at two ends of the functional film. The functional film comprises a hydrophobic region and a hydrophilic region at two ends thereof. The conductive nanomaterial layer has conductive networks formed by a conductive nanomaterial in both the hydrophobic region and the hydrophilic region. An upper electrode (2) and a lower electrode (3) are provided in the hydrophobic region (1a) and the hydrophilic region (1b), respectively. A portion of the hydrophilic region provided with the lower electrode is always immersed in an aqueous solution, and a portion of the hydrophobic region provided with the upper electrode is always exposed from a surface of the aqueous solution. During an evaporation process of water in a region between the upper electrode and the lower electrode, a solute concentration gradient constructed in the hydrophilic region enables a concentration difference diffusion potential to be formed between the two electrodes. The water voltaic power generator effectively utilizes aqueous solutions having different salinities to generate power continuously, and is applicable as a power supply for supplying power to electronic/electrical devices. Further disclosed are a manufacturing method for a water voltaic power generator, and a water voltaic power generator-based integrated electricity generation system.
A: A moisture power generation method and equipment. The method comprises the following steps: pouring a polymer solution into a culture dish and then placing same in an oven to prepare a polymer power generation film (100) (S101); placing the polymer power generation film (100) on a moisture insulated metal electrode (200), and providing a porous top electrode (300) above the polymer power generation film (100) so as to protect the film form of the polymer power generation film (100) and transmit moisture (S102); applying moisture stimulation to the outside of the metal electrode (200) in a single direction, so as to induce the separation of positive and negative ion pairs inside the polymer power generation film (100) and release free moving carriers (S103); and generating a potential difference and current by means of diffusion of carriers from a high concentration region to a low concentration region, thereby outputting electric power to the outside (S104). In the present method, simple and easily available polymer materials which may be bent, stretched and even self-repaired are employed; at the same time, directional moisture stimulation is employed to be able to implement moisture control without requiring assistance from a laser which is expensive to construct; the present method has the advantage of large-scale integration thanks to the simple testing means and the lack of requirement of other expensive external equipment in the testing process.
