Abstract

The invention provides a device for generating hydrogen by electrolyzing water by using a solar thermophotovoltaic system and belongs to the technical field of solar utilization and hydrogen production by electrolysis. The device consists of two main parts: an improved solar thermophotovoltaic system and a water electrolysis-based hydrogen generation system. The improved solar thermophotovoltaic system has higher conversion efficiency and high output power than a system based on common photovoltaic technology and can provide sufficient current power supply for a water electrolysis-based hydrogen generation device. The device uses the power generated by the system in hydrogen generation by electrolysis, the hydrogen is stored, and thus, the problem that the output of the photovoltaic power generator varies with the change of weather and the alternation of day and night. In addition, the cooling of a photovoltaic cell in the device is liquid cooling, the aqueous solution for electrolysis is preheated before being introduced into an electrolytic cell, the power consumption in an electrolysis process is reduced, and thus, the solar utilization rate is further improved.

Description

technical field [0001] The invention belongs to the field of solar thermal photovoltaic utilization, and belongs to a novel solar hydrogen production technology, in particular to a solar thermal photovoltaic hydrogen production device. Background technique [0002] With the development of the global economy and the growth of population, people's demand for energy is also increasing. At present, fossil fuels represented by petroleum and coal are still the main sources of energy. However, due to the non-renewability and limited reserves of fossil fuels, the increasing energy demand has also caused serious energy crises and environmental pollution. [0003] Based on this situation, solar energy, wind energy, biomass energy, geothermal energy, and tidal energy have the advantages of being rich, clean, and renewable, and have received extensive attention from the international community in recent years, especially solar energy, wind energy, and biomass energy. It is regarded as ...
