Description

technical field [0001] The invention belongs to the technology of using solar energy to drive and degrade industrial wastewater to produce hydrogen and electricity, and in particular to a battery capable of simultaneously utilizing solar energy and chemical energy of chemical substances in wastewater to generate electrical energy and hydrogen energy. Background technique [0002] With the development of society, human beings' demand for energy is getting higher and higher, and the non-renewable fossil energy commonly used at present can no longer meet the needs of human beings. Therefore, how to effectively utilize renewable new energy sources such as solar energy and biomass energy has become a major issue in the energy field. Based on this, the development of new and efficient solar or biomass energy conversion devices has become one of the research hotspots. In addition, with the deepening of the industrialization process, our country is facing serious environmental poll...
