- •
Nafion 212 based hybrid membrane with high proton conductivity is synthesised.
- •
Resistance of oxygen reduction reaction at low RH is decreased for hybrid membrane.
- •
Power density of the FC with the hybrid membrane increases with decreasing RH.
- •
Power density of FC with the hybrid membrane is higher as compared with Nafion 212.
- •
The hybrid membrane shows a higher proton conductivity over the entire RH range.
