Integrated Methanol Steam Reformer/Electrochemical Hydrogen Compressor

Abstract

An electrochemical hydrogen compressor (EHC) based on a solid acid electrolyte is built. The EHC operates at temperatures from 230 to 250 °C. The EHC can be used to separate hydrogen from simulated reformate containing more than 2 % CO. The EHC can be directly combined with a methanol steam reformer (MSR). The electrochemical hydrogen compressor with an internal reformer is tested with methanol. The MSR/EHC has the capability of generating hydrogen from methanol, separating hydrogen from impurities, and compressing hydrogen to high pressures.

Effect of airbrush type on sprayed platinum and platinum-cobalt catalyst inks: Benchmarking as PEMFC and performance in an electrochemical hydrogen pump

“…Another use is the recovery of gases from hydrogen-containing mixtures, e.g., oxygen in space vehicles [20], and valuable helium in rocket engine testing facilities [21]. The separation of hydrogen from methane [22] and ethylene [23] mixtures and from CO2-rich reformate [24,25], has also been considered, despite the challenges set by the poisoning of platinum-based catalysts in these environments.…”
