Perspectives on the research progress of bipolar interfacial polyelectrolyte membrane fuel cell

Bipolar interfacial polyelectrolyte membrane fuel cells (BPFCs) are novel devices based on an acidicalkaline bipolar reaction interface. As a result of this innovative bipolar membrane electrode assembly (MEA), BPFCs exhibit outstanding advantages but also present new challenges with regard to the interface. Significant progress has been achieved in BPFCs research in recent years, with the development of key materials and interface technologies. This monograph summarizes the recent advances in MEA technology, including structures, rate-limiting reaction interfaces, water transport mechanisms, and the application of metals other than platinum. These developments in both fundamental theory and primary technologies have established a good foundation for the future research and development of such devices.
