Problems solved by technology

The downside of this technology is that the device only provides the electricity needed to electrolyze water, and at the same time, uses alkaline electrolysis cells, which are less efficient
The disadvantage of this technology is that it needs to separately provide the electric energy required for the SOEC electrolysis process. At the same time, the solar energy needs to be collected to a high temperature of 1000°C, and then transferred to the hydrogen production module through a heat exchanger. Utilization is indirect utilization, and the energy loss in the intermediate heat exchange process is large, which will lead to low solar energy utilization efficiency

Abstract

The invention discloses a high-temperature solid oxide electrolytic cell device coupled with solar photovoltaic light and heat, which includes an SOEC electrolytic cell, a photovoltaic panel, a heat-absorbing cavity, a water vapor channel and the like. Its structure is to open the middle of the photovoltaic panel and fix it with one end of the tubular SOEC electrolytic cell. The outer layer of the tubular electrolytic cell and the other end are wrapped with an insulating layer, and the inner layer is coated with a solar selective absorption coating. The solar photovoltaic panel and the SOEC electrolytic cell A heat-absorbing chamber is formed, and part of the concentrated solar energy is directly irradiated on the photovoltaic panel to generate electricity, and the other part enters the heat-absorbing chamber through a round hole to heat the SOEC electrolytic cell. The thermal cavity provides the required thermal energy. The beneficial effect of the invention is that solar energy can be directly used to realize hydrogen production by electrolysis of water without additional energy input, and meanwhile, the structure is simple and the utilization efficiency of solar energy is high.
