Fuel cells and electrolysers require electrocatalysts to minimize losses during energy conversion processes. It is common practice that researchers rely solely on electrochemical methods to test stability in search of novel electrocatalysts. While degradation can be tracked using such methods, they fail when one aims to understand governing degradation mechanisms responsible for the losses in catalyst performance. Complementary physicochemical techniques are required. One such technique is inductively coupled plasma mass spectrometry (ICP-MS) – the main topic of my talk. [more]
