Mass Spectrometry of Polymer Electrolyte Membrane Fuel Cells [PDF]

Journal of Analytical Methods in Chemistry, 2016
The chemical analysis of processes inside fuel cells under operating conditions in either direct or inverted (electrolysis) mode and their correlation with potentiostatic measurements is a crucial part of understanding fuel cell electrochemistry. We present a relatively simple yet powerful experimental setup for online monitoring of the fuel cell ...
