| 中文摘要: |
| 膜电极(MEA)作为质子交换膜燃料电池(PEMFC)的能量转换单元，在催化剂作用下将化学能转化为电能。铂基催化剂目前仍是商用PEMFC不可替代的催化剂，其中膜电极中铂担载量已成为PEMFC性能评价的一项重要指标。通过对现有PEMFC膜电极铂担载量测试国标方法进行了改进，并研究了PEMFC膜电极铂担载量测试的微波消解前处理方法。与国标方法相比，微波消解-ICP-MS法测定结果的准确性与标准方法相当，测试效率明显提高。 |
| 英文摘要: |
| As the energy conversion unit of proton exchange membrane fuel cell (PEMFC), membrane electrode assembly (MEA) converted chemical energy into electrical energy under the action of catalyst. Platinum-based catalyst was still an irreplaceable catalyst for commercial PEMFC, and the platinum (Pt) loading in membrane electrode had became an important indicator of PEMFC performance evaluation. By improving the existing national standard method for testing the platinum loading of PEMFC membrane electrode, a microwave digestion pretreatment method for testing the platinum loading of PEMFC membrane electrode was developed. Compared with the national standard method, the accuracy of the microwave digestion ICP-MS method is comparable to the standard method, and the testing efficiency is significantly improved. |
