【摘要】

：

石墨烯是由碳原子按六角结构蜂窝状紧密排列而成的二维单层石墨,其独特的结构和优良的理化性质吸引了越来越多研究者的兴趣.石墨烯超强的电子导电性和良好的稳定性也使得它有望成为燃料电池中很好的催化剂载体[1-4].本工作以SiO2为牺牲模板,通过在模板外面均匀包覆Pt纳米粒子和石墨烯,然后除去模板的方法,得到石墨烯包裹Pt的纳米催化剂.制备得到的石墨烯包裹的Pt纳米结构催化剂(GO@Pt)对甲醇氧化显示了

气体加湿度对质子交换膜燃料电池起动电流的影响实验研究

质子交换膜燃料电池在实际应用中不可避免会经历起动、加减速和停机等动态工况.其中在起动过程中,气体加湿度不仅影响电池输出,还影响电池寿命.目前有关加湿度对电池起动的影响研究较少,尤其是耦合了温度,负载等操作工况加湿度对起动电流的实验研究很少.本文研究了不同温度,负载,气体流量和起动初始条件下气体加湿度对起动电流的影响,并采用电流分布测量垫片测量了相应工况条件下局部起动电流,探讨了起动时电池内部的传质
