The development of PEM fuel cells presents a range of complex challenges related to engineering, materials science and economics.

One of these challenges is related to the cost of materials, particularly the platinum-based catalysts used at the electrodes. Researchers are exploring alternatives like platinum alloys or non-precious metal catalysts, but these often suffer from lower performance or durability.

PEM fuel cells are prone to degradation over time, especially under dynamic operating conditions. The membrane can dry out, crack, or degrade chemically, while catalysts can lose activity. Ensuring long-term durability, therefore, remains a critical research focus.
