Title:
PRODUCTION SYSTEM AND PRODUCTION METHOD FOR CATALYST FOR ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2021/193664
Kind Code:
A1
Abstract:
Provided are a production system and a production method which are for a catalyst for an electrode and by which the work of an operator for transferring a catalyst precursor for an electrode can be eliminated and the drying time of the catalyst precursor for an electrode can be shortened. A production system 10 for a catalyst for an electrode includes a production device 12 for a catalyst precursor for an electrode, a washing device 13, and a drying device 14, and has a configuration wherein the drying device 14 is provided with means for executing: an introduction step S31 for introducing the catalyst precursor for an electrode into a container body 202; a drying step S32 for drying the catalyst precursor for an electrode by heating and depressurizing the container body 202, and stirring and mixing the catalyst precursor for an electrode with a stirring blade 204; a cooling step S33 for cooling the catalyst precursor for an electrode by cooling and depressurizing the container body 202, and stirring and mixing the catalyst precursor for an electrode with the stirring blade 204; a slow oxidation step S34 for supplying air into the container body 202 and slowly oxidizing the catalyst precursor for an electrode; and an extraction step S35 for extracting the catalyst precursor for an electrode in the container body 202.
