  In-situ grown carbon nanotubes on carbon paper as an integrated GDL for PEMFCs was fabricated by a chemical vapor deposition process.A series of GDLs with different featureswas obtained by varying growth time from 10 to 55min.The characteristics of the GDL samples involving morphology,contact angle,gas permeability,pore size distribution,through-plane electricalconductivity,in-plane electrical conductivity were evaluated and fuel cell performance of the GDLs was measured by a single cell test with hydrogen/oxygen.

燃料电池全氟磺酸质子交换膜,例如Nafion易受氧自由基轰击导致其化学降解。[1]研究表明,即使Nafion/PTFE复合膜仍无法有效保证Nafion的化学稳定性。且主要膜降解发生区域集中于电池阴极(空气)侧。这种化学降解将导致电池性能衰减,并最终导致膜大面积破损。因此,缓解质子交换膜化学降解已成为燃料电池研究领域的热点。然而对于抗氧化问题,自然界已经提供了解决方案。人体中各种维生素保证了我们不会
