Abstract:
The claimed invention provides an economical cathode for electrolysis and a method of manufacturing the same. The cathode includes a conductive base and a catalyst layer including a catalyst component. The conductive base, e.g. a wire mesh, includes plural intersection portions and is made of nickel. The cathode catalyst layer includes a catalyst component, such as platinum, and is formed by applying an application liquid to the base and drying and solidifying the liquid. The solidified portion of the applied liquid is not formed in the intersection portions of the base, or even if formed, the cross-sectional shape of the solidified portion has mesh-shaped pores with an average porosity of 15% or larger. The base is prepared by preheating to a temperature from 43° C. to 120° C. immediately before applying the application liquid, and thereafter the cathode catalyst layer is formed.
