Process for preparing hydrogen by wind-PV hybrid method and its device

Abstract

The invention discloses a method and device of preparing hydrogen through the complement of the wind and light. The method uses the solar cell pane and wind-driven generator integrated to generate electricity which electrolyzes water to preparing hydrogen. The complement of solar energy and wind energy can compensate the shortage and defect of using single energy, which ensures the uninterrupted power to electrolyze the water. The lowest electric voltage of electrolysis is 2-3V, so the small-sized solar cell pane and wind-driven generator can meet the need. Said device can be assembled flexibly according to different requirements and scales, and it can be built to the small-sized hydrogen energy supply for household or the large-scale supply.

Description

technical field [0001] The invention relates to a method and a device for producing hydrogen by using wind-solar complementary methods. technical background [0002] With the massive exploitation and utilization of oil and natural gas, the problems of energy shortage and energy crisis have attracted more and more people's attention and attention, and the majority of scientific and technological workers are devoting themselves to the research and development of new energy and new products that are environmentally friendly and energy-saving. At present, the development and utilization of solar energy and wind energy have been paid more and more attention by people. Although it is feasible to produce hydrogen by using solar cells to generate electricity by electrolyzing water and using wind energy to generate hydrogen by electrolyzing water, solar cells cannot generate electricity when there is no sun. Wind energy cannot generate electricity when there is no wind, so the electr...

Problems solved by technology

At present, the development and utilization of solar energy and wind energy have been paid more and more attention by people. Although it is feasible to produce hydrogen by using solar cells to generate electricity by electrolyzing water and using wind energy to generate hydrogen by electrolyzing water, solar cells cannot generate electricity when there is no sun. Wind energy cannot generate electricity when there is no wind, so the electrolysis of water cannot obtain a steady stream of current
