Excess energy derived from photosynthesis can be used in plant microbial fuel cell (PMFC) systems as a sustainable alternative for the generation of electricity. In this study, the in situ performance of CAM (Crassulacean acid metabolism) plants in Calama, in the Atacama Desert, was evaluated for energy recovery using PMFCs with stainless steel AISI 316L and Cu as electrodes. The plant species evaluated included , , , , , and . Among the plant species, demonstrated significant potential as an in situ PMFC, showing a maximum cell potential of 0.248 V and a minimum of 0.139 V. In addition, the cumulative energy for recovery was about 9.4 mWh m of the electrode. The use of CAM plants in PMFCs presents a novel approach for green energy generation, as these plants possess an inherent ability to adapt to arid environments and water-scarce areas such as the Atacama Desert climate.
光合作用产生的多余能量可用于植物微生物燃料电池（PMFC）系统，作为一种可持续的发电替代方案。在本研究中，使用以不锈钢AISI 316L和铜为电极的PMFC，对阿塔卡马沙漠卡拉马的景天酸代谢（CAM）植物的原位性能进行了能量回收评估。评估的植物物种包括 、 、 、 、 和 。在这些植物物种中， 作为原位PMFC显示出显著潜力，最大电池电位为0.248 V，最小为0.139 V。此外，电极的累积回收能量约为9.4 mWh/m。在PMFC中使用CAM植物为绿色能源生产提供了一种新方法，因为这些植物具有适应干旱环境和缺水地区（如阿塔卡马沙漠气候）的固有能力。
