| Popis: | Proton-conducting materials based on the MF-4SK membrane and polyantimonic acid have been synthesized; their dielectric properties and conductivity at varying temperature and relative air humidity have been studied. The introduction of polyantimonic acid particles leads to a significant increase in the proton conductivity of the membranes—from 3.2 × 10–5 to 2.5 × 10–4 S/cm—at low humidity. Studies of the proton conductivity as a function of temperature have shown that the doping of the MF-4SK membrane with polyantimonic acid leads to a decrease in the activation energy from 16.8 to 12.9 kJ/mol. |
