4 METHOD OF MANUFACTURING CATALYST ELECTRODE FORMED OF 4 COMPONENTS USING PULSE ELECTRODEPOSITION AND CATALYST ELECTRODE USING THEREOF

摘要

According to an embodiment of the present invention, a method of manufacturing a catalyst electrode formed of 4 components using pulse electrodeposition comprises: a first step of preparing a reference electrode, a relative electrode, and a working electrode immersed in a solution of 15 to 25 degrees containing a precursor of metal ions including nickel, iron, manganese, and coba and a second step of electrodepositing an alloy of 4 components of nickel, iron, manganese, and cobalt on a surface of the working electrode by applying a pulse current to the working electrode. A size of the pulse current is determined according to current density based on an area of the working electrode immersed in the solution, and may be a pulse row configured to repeat a predetermined time with a predetermined period consisting of on time and off time.
