“…One distinct difference between monopolar PEMFCs and BPMFCs is water management during operation. As shown in Figure , BPMFC flooding can occur even when dry gas feeds are utilized, where proper temperature management or introduction of a hydrophilic additive at the BPM IL can reduce the occurrence of flooding. , Initial studies reduced the flooding of BPMFCs by incorporating carbon paper in the IL region at the expense of a large cell resistance . Incorporating thin layers with high hydrophilicity in the IL could increase the power output of BPMFCs, as well as increase the CEL–AEL contact area (see above).…”

Integration of bipolar membranes (BPMs) into electrochemical cells is an established method for acid and base generation, as well as desalinization methods. More recently, BPMs have been recognized for their ability to control the environment of half-reactions, including the maintenance of a pH gradient, without significant loss in efficiency. Over the past few years, significant advances have been made in BPM design, resulting in rapid deployment of BPMs into a wide range of applications, from mineral extraction, to energy storage and conversion frameworks, to ionotronics. Here, we explore the fundamentals of BPM operation and recent methods that have improved the performance and stability of BPMs and provide an overview of the limitations inherent to current BPM-based technologies, with a focus on future directions. Finally, we highlight research areas where BPM integration has enhanced, or is essential for, device operation, showing the versatility, potential, and broad range of research areas impacted by BPMs.
