Document Type and Number:
Japanese Patent JP2023142339
Kind Code:
A
Abstract:
To provide a method for recovering a catalyst layer from an electrode including a conductive substrate and the catalyst layer disposed on the conductive substrate.SOLUTION: A method for recovering a catalyst layer from an electrode including a conductive substrate and the catalyst layer disposed on the conductive substrate includes the step of bringing the electrode including the conductive substrate and the catalyst layer disposed on the conductive substrate into contact with hydrogen chloride gas in an atmosphere of hydrogen chloride gas of 0.1% or more (the step of a hydrogen chloride gas treatment).SELECTED DRAWING: Figure 1
