- •
Effect of bolt pre-loading on deformations is more serious than that of thermal loading.
- •
Bolt pre-loading improves compression ratio of GDL.
- •
For obtaining a maximum performance of GDL, 4 MPa of bolt pre-loading was recommended.
- •
Flow channel volume reduced by bolt pre-loading degrades the efficiency of PEMFC.
