Integrated portable photovoltaic water electrolysis hydrogen production device and hydrogen production system

Abstract

The invention relates to a water electrolysis hydrogen production device, in particular to an integrated portable photovoltaic water electrolysis hydrogen production device and hydrogen production system which comprises a shell, a partition plate fixedly arranged in the shell, a solar cell fixed to the inner side of the shell and an electrode fixed to the solar cell. A cavity formed by the shell is divided into a cathode cavity and an anode cavity by the partition plate, the bottoms of the cathode cavity and the anode cavity are communicated, and electrolyte is stored in the cavity; the electrodes are welded on the solar cells and are respectively fixed in the cathode chamber and the anode chamber through the solar cells; the electrode is immersed in the electrolyte and is higher than the communicating part of the bottom of the cavity; and exhaust ports for exhausting hydrogen or oxygen are respectively formed in the top surface of the shell. Compared with the prior art, a photovoltaic cell and a catalytic material are further tightly combined to form an integrated device, solar energy is converted into hydrogen energy more conveniently, and popularization of hydrogen energy is promoted.

Description

technical field [0001] The invention relates to an electrolysis water hydrogen production device, in particular to an integrated portable photovoltaic water electrolysis hydrogen production device and a hydrogen production system. Background technique [0002] Both photovoltaic power generation and wind power generation are unstable. Unstable energy is a more troublesome thing for the grid. Because electricity is a ready-to-use energy source, it cannot be stored in large quantities. Excess electricity needs to be converted into other forms for storage, such as pumped storage power plants, or it will be wasted. Photovoltaic hydrogen production directly converts electricity into hydrogen energy, so photovoltaic hydrogen production can largely solve the problem of "abandoning light". [0003] Hydrogen energy is known as the clean energy with the most development potential in the 21st century. Hydrogen energy as a secondary energy has the following advantages: ① It can be st...
