Wind-power hydrogen-manufacturing energy storage hydrogen fuel composite cell and power generation method thereof

The invention discloses a wind-power hydrogen-manufacturing energy storage hydrogen fuel composite cell and a power generation method thereof. The cell comprises four working modes according to the intensity of wind. During strong wind, the cell employs a wind-power hydrogen-manufacturing energy storage power generation mode, and the wind power within the rated power is used for the power generation of an external grid, and the remaining wind power is converted into hydrogen for storage. When the intensity of wind is smaller, the cell employs an all-system operation mode, supplies the wind power to the external grid, starts a fuel cell power generation system, and converts the hydrogen energy of the hydrogen storage system into electric energy. When the quality of wind power is poorer, the cell employs a wind-power hydrogen-manufacturing fuel power generation mode, and the wind power is just used for manufacturing hydrogen and the fuel cell power generation system supplies power to the outside at the same time. When wind needs to be abandoned according to the scheduling requirements, the cell employs an independent operation mode, and the fuel cell power generation system enables the stored hydrogen to be converted into high-quality electric energy and enables the high-quality electric energy to be fed to a grid. The cell can effectively iron out the defects of the intermittency and fluctuation of renewable energy power generation (wind power), improves the controllability of output power of an electric field, and improves the stability level of power generation.

Hydrogen Storage System

A Hydrogen storage system comprising storage elements coupled to each other to form one or more containers disposed in a space having a volume V where the volume of each of the storage elements is much smaller than the volume V resulting in the storage elements experiencing reduced stress at their inner surfaces. Thus, Hydrogen can be stored at relatively high pressure within these storage elements due to the reduced stress experienced by their inner surfaces. Consequently, materials having relatively lower tensile strength and stiffness can be used to construct the storage elements of the Hydrogen storage system. Further, the storage elements can be shaped and sized to conform to a volume of space having an arbitrary shape and dimensions.
