👉 The PPFC, or Power Proton Pump Fluid, is a specialized liquid used in proton exchange membrane fuel cells (PPFCs) to facilitate the transport of protons from the anode to the cathode while maintaining proton conductivity and preventing water accumulation. This fluid is typically a mixture of water and a proton-conducting polymer, optimized to ensure efficient ion transport and minimize resistance. The PPFC plays a crucial role in the overall performance and durability of the fuel cell by balancing proton movement and water management, which are critical for maintaining high electrical output and preventing membrane dehydration or flooding.
