聚四氟乙烯(PTFE)对直接甲醇燃料电池的性能起着至关重要的作用。衬垫层和微孔层中聚四氟乙烯含量的存在独立地影响直接甲醇燃料电池的性能。发现PTFE含量影响催化剂利用率和电池阻抗值。在阴极衬底层和阴极微孔层中，PTFE含量为20%是最佳的。直接甲醇燃料电池的性能对阳极微孔层中的聚四氟乙烯含量更为敏感。
Polytetrafluroethylene (PTFE) plays a key role in the performance of a Direct Methanol fuel cell. The presence of PTFE content in the backing layer and the microporous layer affects the performance of a Direct Methanol fuel cell independently. PTFE content is found to affect the catalyst utilization values and cell impedance values. A 20% PTFE content is found to be optimal in the cathode backing layer and cathode microporous layer. The performance of a Direct Methanol fuel cell is found to be more sensitive to the PTFE content in the anode microporous layer.
