DEMS technique characterises fuel cell chemistry
Hiden Analytical announce a new agreement with The University of California, Berkley Laboratory, to produce their novel dual-layer differential electrochemical flow cell for operation with the Hiden HPR-40 DSA membrane inlet mass spectrometer. The combined differential electrochemical mass spectrometry technique (DEMS) is developed for real-time characterisation of electro-catalytic performance with special relevance to fuel cell chemistry, giving fast identification of gaseous and volatile product and intermediates generated during the electrochemical faradaic reactions directly at the electrode/electrolyte interface.
