A tandem electrochemical hydrogen pump system achieves high efficiency in purifying hydrogen from dilute sources. With nearly 100% Faradaic efficiency at high current densities, this technology can produce ultrapure hydrogen (>99.999%) from a 10% feed, potentially reducing capital costs by 95% and energy consumption by 65% compared with conventional methods.
