Electricity Generation from Synthetic Acid-Mine Drainage ...

Acid,-,mine, drainage (AMD) is difficult and costly to treat. We investigated a new approach to AMD ,treatment, using fuel cell technologies to generate electricity while removing iron from the water. Utilizing a recently developed ,microbial, fuel cell architecture, we developed an ,acid,-,mine, drainage fuel cell (AMD-FC) capable of abiotic electricity generation. The AMD-FC operated in fed-batch mode ...
