摘要： Disclosed is a process of preparing an electrode for a solid polymer electrolyte fuel cell which comprises applying a suspension liquid containing a catalyst and ion exchange resin or a catalyst, Ion exchange resin and hydrophobic resin to an electrode substrate, and forming a catalyst layer by drying, sintering the substrate under pressure characterized in that a high boiling point solvent which cannot be removed during the drying procedure is added to the suspension liquid. In this process, the high boiling point solvent such as glycerin and n-butanol which is not removed during the drying step is present in the pressurizing and sintering steps so that the situation of the catalyst layer is maintained constant scarcely influenced by the conditions of the said steps. The above solvent imparts pertinent softness to the ion exchange resin so as not to fill the pores for gas diffusion in the catalyst layer and to sufficiently bond the pieces of the ion exchange having the role of conducting H.sup.+ conduction to obtain the electrode having the excellent electrode characteristics.
