Low temperature solid oxide fuel cell (SOFC) has attracted much attention in recent years due to its potential to meet the cost and reliability requirements for commercialization [1].Perovskite oxide proton conductor BaZr0.1Ce0.7Y0.2O3-δ (BZCY) has become a promising candidate as electrolyte for low temperature SOFC because of its high proton conductivity as well as sufficient chemical and thermal stability in SOFC operation conditions [2].

催化剂载体是燃料电池的重要组成部分,主要起到固定催化剂和辅助催化剂保持大的活性表面积,更重要的是防止催化剂在反应过程中发生聚合等作用.当前,燃料电池主要使用碳黑作为催化剂载体材料,然而在实际操作中碳黑易被腐蚀或氧化而导致催化剂失效.这是长期以来阻碍燃料电池普遍应用的核心问题之一.过渡金属氮化物(TMN)具有高耐腐蚀性,高导电性.我们的研究发现介孔氮化物材料与一般块体氮化物材料在化学性质上,尤其是作

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
