Abstract

The invention discloses a proton exchange membrane electrolytic hydrogen production device based on a photovoltaic cell. The proton exchange membrane electrolytic hydrogen production device comprises a proton exchange membrane electrolytic bath internally provided with a cooling channel, a reaction water inlet in the proton exchange membrane electrolytic bath is connected with a water input mechanism, and the proton exchange membrane electrolytic bath is electrically connected with a power supply mechanism. The power supply mechanism comprises a photovoltaic cell, a voltage converter and an energy storage battery. The water input mechanism comprises a water tank, a deionizer, a water pump, a vaporizer and an ejector, and an electric heater is arranged in the vaporizer. Radiators are arranged on the photovoltaic cell, the voltage converter and the energy storage battery. All the radiators and the cooling channel are communicated in sequence. The outlet of the cooling channel is communicated with a heating medium inlet of the vaporizer, and a heating medium outlet of the vaporizer is connected to the radiator of the photovoltaic cell. The device has the advantages that the hydrogen production efficiency can be effectively improved, and the service life of the whole hydrogen production device can be prolonged.

Description

technical field [0001] The invention relates to the technical field of proton exchange membrane electrolysis hydrogen production equipment. Background technique [0002] Green hydrogen uses renewable energy such as photovoltaics, wind power, and hydropower as the input energy of the water electrolyzer. After converting water into hydrogen and oxygen and separating them, the hydrogen is compressed or liquefied and transported or used on site. There is no carbon emission. There are currently three technical routes for water electrolyzers, namely alkaline electrolyzers, proton exchange membrane electrolyzers, and solid oxide electrolyzers. Their electrolytes, operating temperatures, and conversion efficiencies are different. The proton exchange membrane electrolyzer has the advantages of non-corrosion, low operating temperature, high conversion efficiency, and modularization, and is currently the main research and development direction of green hydrogen production equipment. ...
