Fuel cell technology can be applied to remove pyrite from pyrite containing mine waste (PCMW) and to generate electricity. This study investigated the effect of pH, presence of Acidithiobacillus ferrooxidans, operating temperature, and dissolved oxygen (DO) concentration on the performance of pyrite-fuel cells (PFCs). These factors affect the pyrite dissolution rate, which affects the electron movement for electricity generation, hence electrical performance. The PFCs performance based on the maximum power density and maximum current density, obtained on the 28^th day, was better at pH 2.2 (0.74 mW m^-2, 28 mA m^-2) than at pH 4.3 and pH 6.5 and in the presence of A. ferrooxidans (i.e., biotic PFCs) than in the abiotic PFCs. The biotic PFCs showed more consistent performance regardless of the operating temperature than the abiotic PFCs. The PFCs performance was better at higher DO concentrations (30-33 mg L^-1) than at lower DO concentrations (8-9 and 0-2 mg L^-1); however, gas purging used to adjust DO concentrations could adversely affect the biotic PFCs performance. This study demonstrates that PCMW treatment and electricity generation can be achieved using the fuel cell-based technology, and the PFCs performance can be optimized by adjusting the operating conditions.

燃料电池技术可用于从含矿废物的黄铁矿（PCMW）中去除黄铁矿并发电。这项研究调查了pH值，酸性氧化铁硫杆菌的存在，操作温度和溶解氧（DO）浓度对黄铁矿燃料电池（PFC）性能的影响。这些因素会影响黄铁矿的溶解速度，从而影响电子的运动以产生电能，进而影响电性能。根据最大功率密度和最大电流密度，在28获得的全氟化碳性能^第一天，在pH 2.2（0.74毫瓦米更好^-2，28毫安米^-2）比在pH 4.3和pH 6.5，并在存在的A.杆菌（即生物PFC）比非生物PFC中的含量高。与非生物PFC相比，无论工作温度如何，生物PFC都显示出更一致的性能。在较高的DO浓度（30-33 mg L ^-1）下，PFC的性能要比在较低的DO浓度（8-9和0-2 mg L ^-1）下更好。但是，用于调节溶解氧浓度的气体吹扫会不利地影响生物PFC的性能。这项研究表明，使用基于燃料电池的技术可以实现PCMW处理和发电，并且可以通过调整操作条件来优化PFC的性能。
