Differential electrochemical mass spectrometry (DEMS) involves applying a potential across an electrochemical cell and measuring the resulting current while concurrently analyzing gas products with a mass spectrometer. We used DEMS to investigate the mechanism of carbon support corrosion (CSC) in-situ at the cathode of proton exchange membrane fuel cell (PEMFC). The cathode exhaust gases were sampled with a Hiden Analytical QIC-20 mass spectrometer.
