초록 Recently, the water electrolysis employing solid polymer electrolyte has been widlyinvestigated for hydrogen production. It has been well known that the process ofelectrocatalyst remarkably affect on the performance of water electrolysis. The process,refered to as counter current diffusion, is accomplished by diffusing a metal ion into onesurface of the film while simultaneously diffusing a reducing agent into the oppositesurface of the film. There is no the abrasion of the electrocatalyst in water for thisprocess. In addition, the reaction of preparation of electrocatalyst could be controlled inthis system.In this study, we investigated diffusion of PtCl62- and BH4- in the Nafionmembranefilm. The mathematical model has been utilized to estimate the diffusivity of Pt ion andconcentration within the membrane.
