Water management is important in polymer electrolyte membrane fuel cells, which are emerging as pollution-free energy sources. Because the performance of polymer electrolyte membrane fuel cells depends on water management. The lack of moisture in the polymer electrolyte membrane leads to problems such as reduced conductivity of hydrogen ions in the membrane and the catalyst layer. When less than the appropriate moisture, the proton conductivity of membrane and ionomer decreases, resulting in a decrease in performance. Therefore, it is important to minimize the reduction in fuel cell performance even in low-humidity environments. In this study, we tried to apply hydrophilic carbon paper layer for gas diffusion layer to MEA that can hold the water to operate in low-humidity environments. |
