Silicone based alkaline electrolyte membrane for fuel cell

Abstract We synthesized a new type of alkaline electrolyte membrane by use of aminoethylaminopropylmethyldimethoxysilane via sol–gel technique. The ionic conductivity of the membrane was estimated to be 1.0 × 10 −4  S/cm at 80 °C from AC impedance method. The power density of the fuel cell was 7.6 × 10 −4  W/cm 2 while the current density was 2.2 mA/cm 2 at 0.35 V of potential when the cell was kept at 40 °C.
