After hydrogen production, it can storage and compression for transportation is critical process. In this regard, the electrochemical hydrogen compressor, which allows simultaneous purification and compression of hydrogen, has attracted great attention in recent years. In this study, the compression performance of a single-cell electrochemical hydrogen compressor at different temperature values was investigated. Accordingly, experiments were carried out under low (50–80 °C) and high (120–180 °C) temperature conditions. The optimal polarization curve for electrochemical hydrogen compressors was reached 70 °C at low temperatures and 160 °C at high temperatures. Furthermore, increasing the cell voltage decreases compression time and improves performance. A high compression ratio was achieved at 0.8 V cell voltage. At this voltage, different times are needed at low and high temperatures to compress the hydrogen in the cathode up to 5 bar. Finally, based on the single-cell system's testing results, the stack cell can attain superior compression values.
