Study on the Effect of Polyionic Liquid Functionalized Graphene Oxide As Fillers in Polymer Electrolyte Membrane
Abstract
Within fuel cell systems, the proton exchange membrane (PEM) is an indispensable functional component; therefore, the design and development of PEMs with good mechanical strength and high energy density are essential for the efficient use of energy. In this work, the PIL-SGO filler was prepared and was introduced into the C-SPAEKS polymer matrix to prepare the composite PEMs. The C-S/PIL-SGO-1% membrane had a good comprehensive performance; among them, the tensile strength was 54.61 MPa. The proton conductivity reached the highest with 213.5 mS cm –1 (at 90 °C, 100% RH). The peak power reached 927.33 mW/cm 2, and the OCV was 0.9626 V. The results showed that the introduction of functionalized graphene oxide effectively improved the comprehensive performance of PEMs.
