文摘
- •
We examined PTFE distribution in GDL substrate of polymer electrolyte fuel cells.
- •
The dependence of PTFE distribution on the drying conditions was examined with EDS.
- •
A uniform PTFE distribution in the GDL improved the performance at wet conditions.
- •
The effect of PTFE distribution in the GDL was important even when an MPL was coated.
