Problems solved by technology

This utility model patent can convert air energy into kinetic energy to drive the generator set to rotate. However, due to the energy consumption of the cooler condensation, the energy conversion rate of the system becomes lower, and the generator generates less power, so the actual promotion value is limited.

According to the hydrogen energy power generation system, through the power generation cylinder internally provided with the upperpiston and the lower piston of the movable permanent magnet structure, hydrogen is used as a working medium, the power generation coil wound outside the cylinder body is enabled to generate electricity, the energy of the nature is fully utilized, energy conservation and emission reduction are facilitated, and economic benefits are created.

Description

technical field [0001] The invention belongs to the technical field of energy comprehensive utilization, and relates to a hydrogen energy power generation system of a metal hydrogen storage material. Background technique [0002] The natural world is full of unlimited energy at normal temperature, such as air and sea water, which have potential for development. Most of the energy on the earth comes from the sun. In today's increasingly scarce energy sources, new renewable, green and clean power generation technologies are increasingly valued. Among new energy sources, hydropower and wind power generation technologies are widely used and the technologies are relatively mature. The development potential of hydropower is not great, and the wind power is too scattered, so it can only be used in some specific areas, and the investment of hydropower and wind power generation devices is very large, covering a large area. Air energy has gradually entered people's field of vision. ...
