Improving the flexibility of microbial desalination cells through spatially decoupling anode and cathode

- A microbial desalination cell with decoupled anode and cathode is developed.
- The decoupled configuration facilitates MDC construction and operation.
- The MDC performance can be improved via adjusting anode/cathode ratio.
- The installment position has minor influence on MDC performance.
- The electrical connection can significantly affect current generation.
