Why are PFSA Membranes Preferred in PEM Fuel Cells?
PFSA membranes are preferred in PEM fuel cells for several reasons:
High Proton Conductivity: The sulfonic acid groups provide a high density of acidic sites, facilitating rapid proton exchange. Chemical Stability: The fluorocarbon backbone of PFSA membranes is highly resistant to chemical degradation, even under harsh operating conditions. Mechanical Strength: These membranes can withstand the mechanical stresses encountered during fuel cell operation.
These properties ensure the longevity and efficiency of the fuel cell, making PFSA membranes an optimal choice for this application.
