“…In addition, the reduction of hydrogen peroxide is subject to a two‐electron transfer process, whereas the reduction of oxygen involves a two‐electron transfer or a four‐electron transfer process. In contrast, the reduction activation loss of hydrogen peroxide is lower so as to yield a higher rate of reduction kinetics . Furthermore, the use of hydrogen peroxide solution instead of gaseous oxygen is more able to get rid of water flooding in a passive DMFC …”

Herein, a reduced graphene oxide–supported Prussian Blue (rGO‐PB) composite as the cathode catalyst for a passive direct methanol–hydrogen peroxide fuel cell (DMHPFC) is used. Unlike the conventional passive direct methanol fuel cell (DMFC) with a cathodic catalyst of noble metal platinum (Pt), the new fuel cell uses hydrogen peroxide as the oxidant. This nonnoble metal catalyst has a low cost, high catalytic activity, and high conductivity due to its 3D conductive network. The fuel cell has a theoretical voltage of 1.76 V (higher than 1.21 V related to the traditional DMFC) and can be used in an oxygen‐free environment. Results show that the cell shows good performance with a peak power density of 20.5 mW cm−2 at a higher temperature of 85 °C. The polarization and impedance curves indicate that as the temperature increases, the cell performance improves continuously with the decrease in mass transfer resistance. The discharging tests show a stable cell performance under continuous operation. The cell voltage has an instant response to the change in the current output.

Improving manganese oxides as cathodic catalysts in direct methanol/hydrogen peroxide fuel cells by incorporation of Cu and Fe to promote oxygen reduction (OR) and hydrogen peroxide reduction (HPR) is reported. The Cu‐incorporated and Fe‐incorporated MnxOy were prepared by impregnation and solvothermal processes. From XRD, XPS, and XAS analyses, the obtained MnxOy consisted of MnO2 and mixed phases of Mn3O4 and Mn2O3 from impregnation and solvothermal methods, respectively. The Cu‐incorporated and Fe‐incorporated MnxOy included CuO and Fe2O3, respectively, through both methods. Addition of Cu and Fe decreased the BET surface area and increased the pore sizes as compared to the pristine MnO2. With the Fe : Mn molar ratio of 0.20 : 1, the Fe‐incorporated MnxOy from the solvothermal method presented the highest cathodic peaks under the cyclic voltammogram of HPR and OR at around 0.59 V of 11.59 mA cm−2 and −0.59 V of −12.33 mA cm−2, respectively. Compared to the Cu‐incorporated ones, the highest HPR peak at 0.68 V of 9.20 mA cm−2 and the highest OR peak at −0.59 V of −6.99 mA cm−2 were obtained from the Cu‐incorporated MnxOy prepared through the solvothermal method at the Cu : Mn molar ratio of 0.15 : 1. Incorporating Cu or Fe into MnO2 brought the improvement of electrocatalytic activity for HPR and OR. The Cu‐incorporated and Fe‐incorporated MnxOy from both methods showed a higher power density of μ‐DMFC than the pristine MnO2.

Catalytic valveless micropumps, and membraneless fuel cells are the class of devices that utilize the decomposition of hydrogen peroxide (H2O2) into water and oxygen. Nonetheless, a significant obstacle that endures within the discipline pertains to the pragmatic open circuit potential (OCP) of hydrogen peroxide FCs (H2O2 FCs), which fails to meet the theoretical OCP. Additionally, bubble formation significantly contributes to this disparity, as it disrupts the electrolyte's uniformity and interferes with reaction dynamics. In addition, issues such as catalyst degradation and poor kinetics can impact the overall cell efficiency. The development of high‐performance H2O2‐FCs necessitates the incorporation of selective electrocatalysts with a high surface area. However, porous micro‐structures of the electrode impedes the transport of fuel and the removal of reaction byproducts, thereby hindering the attainment of technologically significant rates. To address these challenges, including bubble formation, the review highlights the potential of integrating electrokinetic and bubble‐driven micropumps. An alternative approach involves the spatiotemporal separation of fuel and oxidizer through the use of laminar flow‐based fuel cell (LFFC). The present review addresses multifaceted challenges of H2O2‐powered FCs, and proposes integration of electrokinetic and bubble‐driven micropumps, emphasizing the critical role of bubble management in improving H2O2 FC performance.
