PRODUCTION SYSTEM AND PRODUCTION METHOD FOR CATALYST FOR ELECTRODE

Provided are an electrode catalyst production system and production method capable of omitting the operation for an operator to transfer an electrode catalyst precursor, and shortening a drying time of the electrode catalyst precursor. The invention is configured as follows. An electrode catalyst production system 10 has an electrode catalyst precursor production device 12, a washing device 13 and a drying device 14. The drying device 14 includes executors for executing: an introduction step S31 for introducing an electrode catalyst precursor into a container main body 202; a drying processing step S32 for drying the electrode catalyst precursor by heating and depressurizing the container main body 202, and stirring and mixing the electrode catalyst precursor with a stirring blade 204; a cooling step S33 for cooling the electrode catalyst precursor by cooling and depressurizing the container main body 202, and stirring and mixing the electrode catalyst precursor with the stirring blade; a slow oxidation step S34 for performing a slow oxidation treatment on the electrode catalyst precursor by supplying air to the container main body 202; and a retrieving step S35 for retrieving the electrode catalyst precursor inside the container main body 202.
