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.
