Abstract

The invention discloses a multi-energy complemented hybrid power generation system of a wind, light and proton exchange membrane fuel battery, and a method. A power generation proportion of solar energy and wind power is continuously increased; a situation of wind and light abandoning is very rigorous; the reliability, a performance index and a life cycle of a proton exchange membrane fuel battery are greatly improved along with technical breakthrough; and a commercial operation stage is entered. Abandoned wind and abandoned light energy sources are comprehensively utilized by the proton exchange membrane fuel battery; water is electrolyzed by surplus power generated by a photovoltaic array and a wind power generator to generate hydrogen and oxygen; an electrochemical reaction is performed in the proton exchange membrane fuel battery; chemical energy of fuel is directly converted into electric energy; heat engine carnot cycling is not required; a reaction product is the water; and the clean and environment-friendly multi-energy complemented hybrid power generation system of the wind, light and proton exchange membrane fuel battery is formed.

Description

technical field [0001] The invention relates to a wind, light, and proton exchange membrane fuel cell multi-energy complementary hybrid power generation system and method, which can make full use of abandoned wind and light energy and convert it into hydrogen energy for storage. The load demand under peak or no wind and no light belongs to the technical field of multi-energy complementary hybrid power generation. Background technique [0002] With the deepening of energy structure adjustment and supply-side structural reform, in order to further increase the proportion of clean energy, it is bound to increase the proportion of solar energy and wind power generation. However, limited by factors such as power supply, grid, and load, wind, photovoltaic The problem of renewable energy consumption has always been an important task for the development of renewable energy. At present, the situation of abandoning wind and light is still severe. With technological breakthroughs, pro...
