| 제목 | Preparation of ion-conducting composite membranes for hydrogen based energy conversion devices |
| 초록 | An approach to minimize areal resistance of film-type polymeric electrolytes is to make film thickness as thin as possible. Free standing polymeric electrolytes, however, show low mechanical properties. Thus, composite membranes could be used by impregnating polymeric electrolytes into thin porous substrates. Polytetrafluoroethylene(PTFE) is the most widely used as substrate for reinforced composite membranes. However, it is difficult to uniformly impregnate the hydrophilic ionomer solution because the PTFE surface has a hydrophobic nature. In this study, a technique to impregnate polymeric electrolytes into porous substrates was intensively developed so as to prepare void-free composite membranes.
