N2 - Catalytic valveless micropumps, and membraneless fuel cells are the class ofdevices that utilize the decomposition of hydrogen peroxide (H2O2) into waterand oxygen. Nonetheless, a significant obstacle that endures within thediscipline pertains to the pragmatic open circuit potential (OCP) of hydrogenperoxide FCs (H2O2 FCs), which fails to meet the theoretical OCP.Additionally, bubble formation significantly contributes to this disparity, as itdisrupts the electrolyte’s uniformity and interferes with reaction dynamics. Inaddition, issues such as catalyst degradation and poor kinetics can impact theoverall cell efficiency. The development of high-performance H2O2-FCsnecessitates the incorporation of selective electrocatalysts with a high surfacearea. However, porous micro-structures of the electrode impedes thetransport of fuel and the removal of reaction byproducts, thereby hinderingthe attainment of technologically significant rates. To address thesechallenges, including bubble formation, the review highlights the potential ofintegrating electrokinetic and bubble-driven micropumps. An alternativeapproach involves the spatiotemporal separation of fuel and oxidizer throughthe use of laminar flow-based fuel cell (LFFC). The present review addressesmultifaceted challenges of H2O2-powered FCs, and proposes integration ofelectrokinetic and bubble-driven micropumps, emphasizing the critical role ofbubble management in improving H2O2 FC performance.
