AB  - 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 28th 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.
