PARAMETER OPTIMIZATION OF A PBI MEMBRANE-BASED HIGH TEMPERATURE-ELECTROCHEMICAL HYDROGEN COMPRESSOR FED WITH H2 AND CO MIXTURE

Abstract

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.
