- •
Various reported tortuosity factors in Bruggeman correlation has been investigated.
- •
The variation of tortuosity factors will lead to great difference in cell performance.
- •
The cell performance shows high sensitivity to tortuosity factors of cathode side.
- •
Improving the gas diffusion of cathode side can greatly enhance the cell performance.
