The present invention relates to a method for preparing polyarylsulfone ether on the basis of a double-end-capping method. In the method, a bifunctional phenol and a bifunctional halogenated arylsulfone are used as raw materials, and are subjected to a condensation polymerization reaction in an organic solvent in the presence of an inorganic caustic alkali or inorganic caustic salt to prepare polyarylsulfone ether. After the molecular weight of the polyarylsulfone ether reaches a preset value, a halogen-eliminating metal phenate end-capping agent is added to a polymerization system, thereby removing an end group of a halogen atom and also achieving control over the molecular weight distribution during polymerization; and after a predetermined molecular weight is reached by means of condensation polymerization, a high-activity metal-phenate-removing aromatic end-capping agent is added to the polymerization system to remove a metal phenate end group and terminate the condensation polymerization reaction, and to make the polyarylsulfone ether have an aromatic end group and also contain necessary functional groups during end-capping. The obtained polyarylsulfone ether not only has good comprehensive performance, but can also meet the subsequent requirements of application fields; and by using end-capping agents containing corresponding functional groups, the requirements of different application scenarios for the polyarylsulfone ether can be met by means of the end-capping reacti

The invention relates to a method and a device for ascertaining the conditions underlying a degradation of galvanic cell assemblies, in particular fuel cell assemblies (10), of a stationary or preferably mobile system using electrochemical impedance spectroscopy, wherein an electric input signal with a frequency which changes within an overall frequency range, in particular a frequency range between 10 mHz and 100 kHz, 200 kHz, or 300 kHz, is applied to the galvanic cell assembly, in particular the fuel cell assembly, and an electric output signal which is produced on the output side of the cell assembly in response thereto is measured with respect to amplitude and frequency and is analyzed using a comparison with previously captured reference values. Improved application possibilities for the method and the device are achieved on the basis of the electrochemical impedance spectroscopy in that the electric output signal is measured only in mutually spaced frequency bands (22) about specific frequency points (21) within the overall frequency range on which the measurement is based, and the analysis is based on the output signal.
