Enhanced Proton Conductivity of a Zn(II)-Based MOF/Aquivion Composite Membrane for PEMFC Applications

“…The transferable Brønsted acidic sites of the Aquivion matrix and the hydrophilic (Me 2 NH 2 ) + cations residing within the MOF-1 structure behaved as ion-exchange sites under humidified conditions. 42 The IEC improved with increasing weight percentages of MOF-1 because of the increase of the proton carrier. The peak IEC value was observed for the 1 wt % MOF-1/Aquivion membrane.…”

“…The density of the transferable acid groups in the membrane is shown by the IEC values. , Figure shows the IEC values of the Aquivion membrane and various wt % MOF-1/Aquivion composite membranes. The transferable Brønsted acidic sites of the Aquivion matrix and the hydrophilic (Me 2 NH 2 ) + cations residing within the MOF-1 structure behaved as ion-exchange sites under humidified conditions . The IEC improved with increasing weight percentages of MOF-1 because of the increase of the proton carrier.…”
