Progress in the study of bipolar plates/conductive fillers

Abstract

Proton exchange fuel cell (PEMFC) is an efficient, low-pollution and clean energy source that can directly convert chemical energy into electrical energy, and it has a broad application prospect in the future of on-board driving power supply, portable power supply and power station for home use. As one of the key components of PEMFC, the choice of material has a great influence on its performance. In order to find new materials for bipolar plates with excellent performance and low cost, this paper reviews the research progress of conductive filler/resin composite bipolar plates for PEMFCs, and summarizes the relevant properties of the current composite bipolar plates with different resins/different conductive fillers.
