研究了聚合物电解质燃料电池（pefc）用微加工金属薄膜气体扩散层（GDL）的可行性和设计参数效应。钛薄膜因其对电池运行的耐久性而被广泛使用。在各种加湿和细胞温度行为下的细胞操作特性进行了检查，以显示水管理的重要性。研究了设计参数（如通孔直径、通孔图案和薄膜厚度）对器件性能的影响，揭示了设计优化对器件性能的影响。GDL有望用于过电位因素的严格建模。(c) 2005 Elsevier B.V.版权所有
Feasibility and the design parameter effect are examined for micromachined metallic thin film gas diffusion layer (GDL) for polymer electrolyte fuel cells (PEFCs). Titanium thin film is used at present due to its endurance to the cell operation. Cell operation characteristics under various humidification and cell temperature behavior are examined to show the importance of water management. Impact of design parameters such as through-hole diameter, through-hole patterning and the thin film thickness have been investigated to show the parameter dependence as well as the possible high performance with design optimization. The GDL is expected to be used for rigorous modeling of overpotential factors. (c) 2005 Elsevier B.V. All rights reserved.
