摘要：An attempt has been made in the present work to develop a new Polyethylene oxide (PEO) based Solidpolymer electrolyte membrane, (PEO+KHCO3) by Isothermal immersion- technique. Several experimental techniquessuch as IR, composition dependence conductivity, temperature dependence conductivity in the temperature range of308- 368K and transport number measurements were employed to characterize this polymer electrolyte membranesystem. The IR studies confirm the salvation of K+ ion with PEO. The conductivity of the (PEO+KHCO3) electrolytewas found to be about 3 times larger than that of pure PEO at room temperature. The transference data indicated thatthe charge transport in these polymer electrolyte systems is predominantly due to ions. Using this conducting polymerelectrolyte membrane, a polymer electrolyte membrane (PEM) Fuel cell stack was fabricated with the configurationanode/polymer electrolyte/cathode and studied its I-V Characteristics. The results of these investigations are reported inthis present paper.
