What Are the Challenges in Proton Exchange Membrane Catalysis?
One of the primary challenges in PEM catalysis is the [durability]() and longevity of the catalysts. Over time, catalysts can degrade or become poisoned by impurities, reducing their effectiveness. Another challenge is the high cost associated with platinum-based catalysts. Researchers are investigating non-precious metal alternatives and composite materials to address these issues. Additionally, optimizing the membrane's [proton conductivity]() and mechanical properties remains a crucial area of development.
