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.

Abstract: A method for manufacturing an electrode, which can suppress waste of electrode substrate, prevent impairment of operability, improve flatness and the like, and reliably prevent falling off thereof, and simultaneously can prevent wrinkles and bulges of the electrode caused by the heat treatment and the like, thereby manufacturing a higher-quality electrode. The method includes: preparing a rectangular plate-like electrode substrate having attachment portions at two ends including opposing sides by linearly bending two parts so that each part has an overall even side; holding the attachment portions by the suspension jig and a lower jig each being provided with a movement restriction portion with which a leading end of each attachment portion comes into contact, thereby maintaining the electrode substrate in a suspended state; and performing at least heat treatment on the suspended electrode substrate so as to manufacture a portion for an electrode.

Abstract: Provided is an economical cathode for electrolysis in which the amount of expensive cathode catalyst component used in a base is effectively reduced, without damaging the performance of the cathode, and an increase in the amount of cathode catalyst consumed due to long-term electrolysis can be prevented. A cathode for electrolysis and a simple method for manufacturing the cathode for electrolysis are provided. The cathode for electrolysis includes a conductive base, which is, for example, a wire mesh, includes a plurality of intersection portions, and is made of nickel and a cathode catalyst layer that includes a catalyst component, such as platinum, and is formed by applying an application liquid to the base and dying and solidifying the application liquid.
