Abstract:
Electrochemical H2 pumping with ultralow H2 concentrations (such as 1-10 ppm) was experimentally demonstrated for prominent current response (0.42-3.1 µA), under a low cell voltage at a high flow rate, supported by Multiphysics simulation. The findings in this work may extend the application of H2 pumping to H2 detection and other advanced electrochemical systems.

663
Controlled-potential coulometry, also known as potentiostatic coulometry, employs a three-electrode system in which the working electrode's potential is precisely regulated using a potentiostat. Platinum working electrodes are utilized for positive potentials, while mercury pool electrodes are favored for extremely negative potentials. The platinum counter electrode is separated from the analyte using a membrane or salt bridge to avoid interference in the analysis.

A concentration cell is a type of a voltaic cell constructed by connecting two almost identical half-cells, both based on the same half-reaction and using the same electrode, differing only in the concentration of one redox species. A concentration cell's potential, therefore, is determined only by the concentration difference of the particular redox species.
