Research Progress and Prospects of Bipolar Plate Materials for Proton Exchange Membrane Fuel Cells

Abstract

The bipolar plate is an essential component of proton exchange membrane fuel cells (PEMFC), with crucial functions such as gas separation, cooling, conduction, heat dissipation, and water ejection. The advancement of proton exchange membrane fuel cell technology relies on the performance of the bipolar plate. Recognizing the significance of bipolar plates for PEMFC functionality, researchers have been striving to create bipolar plates with high conductivity, good gas tightness, appropriate mechanical properties, corrosion resistance, and cost-effectiveness. This paper provides a detailed analysis of recent research progress on bipolar plates, aiming to contribute to the development of new and optimized products in the PEM fuel cell industry. The study in this paper focuses on three aspects: (1) Introduction to the polymer electrolyte membrane (PEM) fuel cell technology system and development directions, (2) Discussion on the structure of carbon-based fillers and their impact on the final electrical performance of composite bipolar plates, (3) Introduction to the Dual Percolation Effects of resins and Their Applications.
