Operation at high current density of polymer electrolyte membrane electrolysis cell (PEMEC) can reduce its electrode area and capital expense. The operation is limited by the limiting (LCD), where voltage abruptly increases. Effects operating temperature pressure on LCD were evaluated in a lab-scale PEMEC within range from 70 to 90 °C 0.1 0.3 MPa. Also, theoretical model was developed predict LCD, clarify what determines how conditions influence LCD. analysis suggests that when close water...
The numerical analysis conducted in this study proposes a guideline to maximize the high-temperature effect, which is expected reduce electrolysis voltage of polymer electrolyte membrane water electrolyzer. High-temperature operation intuitively thought activation overvoltages. However, further consideration predicts that high temperature, especially temperature higher than saturated regulated pressure, decreases liquid saturation and causes shortage water, leading large increase This...
