Description

technical field [0001] The invention belongs to the field of plant-microbial fuel cells, in particular to an anode photosynthetic solar fuel cell system. Background technique [0002] After the industrial revolution, the speed of energy utilization worldwide has shown exponential growth. Traditional energy is based on fossil energy. The current common fossil energy coal, oil, and natural gas will be nearly exhausted in recent decades, and the rapid development of the modern economy relies heavily on traditional energy for energy utilization. The continuous increase in demand has further increased the contradiction between supply and demand, so the research and development of renewable energy is imminent. In response to energy shortages and pollution crises, countries are developing a series of new and alternative energy sources, and various new energy technologies have been proposed one after another. It mainly includes fuel cell technology, hydrogen fuel, methanol, biodie...
