The electro catalyst layer is crucial since it affects the fuel cell's total cost. Pt is commonly used as a catalyst in PEMFCs
to speed up the chemical process. A tiny quantity of Nafion (Sulfonated Polytetrafluoroethylene) holds these catalysts
together [21]. Electrons go from the anode to the cathode through an externally linked circuit in the FC. At the same time,
protons travel through the electrolyte to reach the cathode [22]. The electrons, protons, and oxygen finally make their way to
the cathode, where they are reduced. These types of FC [23] have benefits such as quick start-up, strong mechanical
construction, a broad range of power output from mW to kW scale, and simple scale-up. Slow oxygen reduction kinetics,
poor heat and water management, CO poisoning, and the necessity for high quality hydrogen as a fuel are among drawbacks
of PEMFCs. Regardless, PEMFC is a viable contender for replacing gasoline engines in automobiles and aircraft [24].
