摘要: This invention provides an electrode for a fuel cell comprising a catalyst layer obtained by a first step of homogeneously mixing carbon supporting platinum which is an electrode catalyst, an alcohol solution of an ion conductive component which is a solid polymer electrolytic membrane component, and an organic solvent, by means of a stirrer having a grinding effect to produce electrode paste in which the carbon is highly dispersed; a second step of stirring said electrode paste by means of a three-dimensional vibrating stirrer in order to obtain highly structured carbon on which platinum is supported; and a third step of coating a gas diffusion electrode material and/or a solid polymer electrolytic membrane with the electrode paste in which the carbon is highly structured, followed by removal of the organic solvent.
