Abstract:
Electrochemical hydrogen pump (EIIP) is capable of extracting hydrogen from miscellaneous gases and compress it to very high pressures. Since during its operation it does not produce water the performance is heavily dependent on humidity of the membrane. Online humidity estimation is performed by means of performing electrochemical impedance spectroscopy (EIS).
