, 2011 本发明公开了一种质子交换膜燃料电池膜电极(MEA)中炭腐蚀情况的在线检测方法。该方法采用COx转化炉和气体检测设备测试MEA在实际运行过程中炭腐蚀情况。将正常运行的燃料电池的阳极出口的尾气或阴极出口的尾气通过气体控制器进入COx转化炉，经过转化炉转化后的尾气进入气体检测设备，从而得到炭腐蚀的情况。该测试方法包括尾气控制器，气体转化炉，催化剂，温度控制器，进样系统，气体检测设备及气体管路。本检测方法能实现在线自动检测MEA中炭腐蚀产物的浓度，能及时、准确反映炭的腐蚀情况，并且测试过程简单、易控、重复性好 ...

, 2018 以纳米SiO_2为载体,采用层层自组装技术在其表面交替沉积天然聚电解质壳聚糖和环保型缓蚀剂聚天冬氨酸,制备出纳米容器,将纳米容器分散到环氧涂层中获得改性环氧涂层。通过Zeta电位、扫描电子显微镜(SEM)和Fourier转换红外线光谱仪(FT-IR)对纳米容器进行了表征,利用电化学阻抗技术对比研究了普通环氧涂层与改性环氧涂层/Q235碳钢体系在3.5%(质量分数)NaCl溶液中的腐蚀行为。结果表明,纳米容器可以有效减缓海水在环氧涂层内部的扩散,提高环氧涂层的电阻,从而增大腐蚀反应阻力 ...
