磷酸型燃料电池中电解质性能的研究（Ⅱ）

, 1999
简要叙述了磷酸型燃料电池（ＰＡＦＣ）最新研究进展，介绍了在相同条件下比较氢和甲烷作为燃料在磷酸（８５％）电解质和Ａ型电解质（多氟磷酸和磷酸的混合物）中的电化学行为。在１３０℃，将塌解质燃料电池的输出特性与磷酸（８５％）电解质燃料电池进行比较。全部 试验在有参比电极的三电极试验电池中进行，试验遇极采用自制电极的三电极辅助电极采用光亮铂电极或者镀铂电极，参比电极采用动态氢电极。测量系统是由Ｄ、Ｈ ...

质子交换膜燃料电池用梯度结构气体扩散电极

, 2010
依次用m（Pt）：m（Nafion）=0．4：0．8、0．6：0．6、0．8：0．4和1．0：0．2的催化剂料液分层涂覆，制备了梯度结构气体扩散电极；通过伏安曲线、扫描电镜（SEM）和循环伏安（CV）等方法，研究了电极结构对质子交换膜燃料电池（PEMFC）性能的影响。该梯度结构电极具有电子传导速度快、质子传递通道多的特点，催化剂Pt的利用率比亲水电极提高了32％，且能扩大催化反应的三相界面，提高PEMFC的性能。在电流密度为500mA／cm^2、1000mA／cm。时，使用梯度结构电极的PEM ...
