Abstract

The invention provides a fluctuation type power input water electrolysis hydrogen production method and device. The method comprises the step of: distributing fluctuation type input power into electrolysis power and heat storage power, wherein the electrolysis power is used for providing electric energy for hydrogen production by electrolyzing water; and the heat storage power is converted into heat energy for providing starting energy for hydrogen production by electrolyzing water, so that the cold starting speed of hydrogen production by electrolyzing water is increased. According to the method, fluctuation type power is distributed into heat storage power, and the heat storage power is converted into heat energy for providing starting energy for hydrogen production by electrolyzing water, so that the cold starting speed of water electrolysis hydrogen production can be remarkably increased, the system cannot be stopped, frequent start and stop of the system caused by fluctuation typepower input are effectively avoided, the concentration change of hydrogen and oxygen cannot be affected, and the yield and quality of hydrogen and continuous and safe production are guaranteed.
