| 제목 | An inorganic-organic composite proton exchange membrane for high temperature Polymer Electrolyte Membrane fuel cells by using electrospinning |
| 초록 | An inorganic-organic composite membrane has been synthesized to improve thermal stability, hydrogen ion conductivity and polymer electrolyte membrane fuel cell(PEMFC) performance at high temperature. inorganic-organic composite membranes were fabricated from in three main steps. Frist, an inoranic-organic precursor solution were prepared from the mixed solution containing SiO2 using the sol-gel process and SPEEK in DMF solvent. Second, inorganic-organic(SPEEK-SiO2) membrane is made from this precersor solution using an electrospinning method. Third, electrospun inorganic-organic(SPEEK-SiO2) membrane impregnated with Nafion solution. PEMFC test results show that the Nafion impregnated electrospun inorganic-organic membrane improved thermal stabillity, proton conductivity and good performance at high temperature and low humidity. |
