“…For example, they account for almost half the price of a hydrogen refueling station [78]. Therefore, electrochemical compressors, based on technology similar to proton-exchange membrane fuel cells, and thermally driven adsorption compressors are likely to solve the above-mentioned drawbacks of mechanical hydrogen compression [18,79,80]. Thermally driven compression of hydrogen by adsorption-desorption (Figure 7b) consists of physically adsorbing hydrogen onto a microporous material, which is packed into a previously cooled high-pressure reservoir, e.g.…”

Selective ionic separations represent an increasingly important technical area for the strategic interests of the U.S. economy�for example, securing critical minerals and materials and circular economy aspirations that include recovering organic acids from processed biomass. This work disseminates bipolar membrane (BPM) capacitive deionization for selective ionic separations from multicomponent, ionic species mixtures. The selective separations are guided by the Pourbaix diagram and acid−base equilibria principles. BPM capacitive deionization was demonstrated to generate alkaline or acidic process streams depending upon the location of the BPM in the electrochemical cell. The role of system operating parameters, such as the cell voltage, residence time, and feed concentration on effluent stream pH was studied. It was observed that the pH adjustment in BPM-CDI/ MCDI (MCDI, membrane capacitive deionization) was more sensitive to the cell voltage when compared to the process stream residence time and salt feed concentration. The BPM-MCDI gave over 6 times higher percentage of copper(II) removal when compared to sodium ion removal from brine mixtures. Finally, BPM-MCDI demonstrated over 40% greater removal for copper ions from brine mixtures and fivefold higher removal for itaconic acid from brine mixtures when benchmarked against a traditional flow-by-MCDI setup.

“…Electrochemical H 2 purifier (ECHP) systems can be used not only for purification but also for H 2 pressurization. [20][21][22] ECHP has many advantages over traditional purification methods. For example, they are environmentally friendly with almost zero pollutants, they work silently, and if desired, both compression and purification can be achieved in a single-step process at the same time.…”

Summary In the present work, the purification of hydrogen from a hydrogen/carbon dioxide/carbon monoxide (H2:CO2:CO) mixture by a high‐temperature electrochemical purification (HT‐ECHP) system is examined. Electrochemical H2 purification experiments were carried out in the temperature range of 140‐180°C. The effects of the molar ratio of the gases in the mixture (H2:CO2:CO‐75:25:0, H2:CO2:CO‐72:26:2,0 H2:CO2:CO‐75:22:3, H2:CO2:CO‐75:20:5, H2:CO2:CO‐97:0:3, H2:CO2:CO‐95:0:5) and the operating temperature on the electrochemical H2 separation were investigated. As a result of the electrochemical H2 purification experiments, it was determined that the operating temperature is the most important parameter affecting the performance. According to the results obtained, H2 purity of 99.999% was achieved at 160°C with the reformate gas mixture containing 72% H2, 26% CO2, and 2% CO by volume. According to the polarization curves of the gas mixtures containing CO, high current densities at low voltage were reached at 180°C, and it was observed that the performance increased as the temperature increased, whereas the gas mixture without CO gave the best performance at 160°C.
