    PARAMETER OPTIMIZATION OF A PBI MEMBRANE-BASED HIGH TEMPERATURE-ELECTROCHEMICAL HYDROGEN COMPRESSOR FED WITH H2 AND CO MIXTURE
    (International Association for Hydrogen Energy, IAHE, 2022) Kuzu,C.; Ozgur Colpan,C.; Durmuş,G.N.B.; Devrim,Y.; Mechanical Engineering; Energy Systems Engineering
    In today's world, the increase in the amount of energy needed with the increase in the human population and the depletion of fossil fuels has pushed researchers to search for alternative fuels. Hydrogen is expected to take an important share among the alternative fuels in the future. However, it has some challenges in terms of its storage and pressurization. In this study, the effect of back diffusion on the performance of a PBI membrane-based electrochemical hydrogen compressor operating at 160 °C. Pressure values are calculated and validated with experimental results; and the change of flux, voltage and cell efficiency with time are presented. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.

    DEVELOPMENT OF BIMETALLIC ELECTROCATALYSTS FOR HIGH-TEMPERATURE ELECTROCHEMICAL HYDROGEN PURIFICATION
    (International Association for Hydrogen Energy, IAHE, 2022) Bal,İ.B.; Durmuş,G.N.B.; Devrim,Y.; Mechanical Engineering; Energy Systems Engineering
    In this study, PtRu/GNP, PtIr/GNP, and RuIr/GNP bimetallic catalysts were synthesized by microwave-assisted synthesis method, and their performances on the high-temperature electrochemical hydrogen purification (HT-ECHP) were compared. The structural and electrochemical characteristics of the bimetallic catalysts were examined by the TGA, XRD, XPS, and CV techniques. ECHP Tests were performed with reformate gas mixtures containing hydrogen (H2), carbon monoxide (CO), and carbon dioxide (CO2) at temperatures between 140-180°C. The gas at the exit of the ECHP cell was analyzed with the gas chromatography device (GC), and high H2 purity was achieved. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.

    ELECTROCHEMICAL HYDROGEN SEPARATION FROM REFORMATE USING POLYBENZIMIDAZOLE/MOF COMPOSITE MEMBRANES
    (International Association for Hydrogen Energy, IAHE, 2022) Durmuş,G.N.B.; Eren,E.O.; Devrim,Y.; Ozgur Colpan,C.; Özkan,N.; Mechanical Engineering; Energy Systems Engineering
    This study introduces the experimental results of a high-temperature electrochemical hydrogen purification (ECHP) cell through poly 2.2-m-phenylene-5.5-bibenzimidazole/metal organic framework (PBI/MOF) composite membranes in the temperature range of 140°C-180°C. Synthesis of ZIF-8 and UiO-66 MOFs was conducted through a typical solvothermal method, and composite membranes containing 2.5 wt. %. MOF was fabricated. Experiments were conducted with pure hydrogen (H2) and reformate gas mixtures containing H2, carbon monoxide (CO), and carbon dioxide (CO2). A gas chromatography device (GC) was used to analyze the gas composition at the exit of the ECHP cell. The final output H2 purity was found to be >99.9 % for the H2/CO2/CO mixed-phase and >99.7% for the H2/CO mixed phase. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.
