“…The methanol oxidation reaction can be catalyzed by using PANI as an anode material in DMFCs (Papiya, Pattanayak, Kumar, Kumar, & Kundu, 2018). PANI can be employed as a cathode material in MFCs, enhancing the fuel cell's electrochemical performance and stability (Papiya et al, 2018;Sudarsono et al, 2022). PANI composites and hydrogels have been employed in numerous research investigations for fuel cells.…”

Including supercapacitors, rechargeable batteries, and fuel cells, conducting polyaniline (PANI) has been widely used in electrochemical energy storage and conversion technologies due to its high conductivity, ease of synthesis, high flexibility, low cost, and distinctive redox properties. Because of its poor stability as a super-capacitive electrode, pure PANI cannot keep up with the rising demands for more N-active sites, better power/energy densities, and more stable molecular structures. These drawbacks as a super-capacitive electrode can be overcome by combining PANI with other active materials such as carbon compounds, metal compounds, and other conducting polymers (CPs). Recent PANI research focuses mainly on PANI-modified composite electrodes and supported composite electrocatalysts for fuel cells and rechargeable batteries, respectively. Due to the synergistic effect, PANI-based composites with various unique structures have shown superior electrochemical performance in supercapacitors, rechargeable batteries, and fuel cells. PANI typically functions as a conductive layer and network in different PANI-based composite structures. This review also discusses N-doped carbon materials produced from PANI because they are frequently employed as metal-free electrocatalysts for fuel cells. We conclude by providing a quick summary of upcoming developments and future research directions in PANI

“…However, the performance of PANI‐based Fe‐N‐C is still unsatisfactory in acidic media [17, 18]. Wulandhari Sudarsono and co‐workers synthesized a Fe‐PANI catalyst derived from reduced graphene oxide, and the E 1/2 is still 50 mV negative than that of Pt/C [19]. Unsatisfied ORR performance in acidic media limits the application of PANI‐based Fe‐N‐C catalysts in DMFCs, and the synthesis procedure deserves further optimization.…”

Fe‐N‐C catalysts show great potential to replace Pt/C in oxygen reduction reaction (ORR). Polyaniline (PANI) is an ideal precursor with an abundant and homogeneous distribution of nitrogen sources. However, Fe‐N‐C based on PANI suffers from an unsatisfied performance in acidic media. Herein, a facile zinc‐assisted synthesis of Fe‐N‐C based on PANI was reported in this paper. ZnCl2 templates can be removed completely in the pyrolysis procedure, creating abundant porous structures to accelerate the mass transfer and boost ORR performance. Fe‐N‐C‐2 with the adequate and optimizing amount of zinc shows an excellent ORR performance (E1/2 = 0.91 V in alkaline and E1/2 = 0.825 V in acidic media) compared with Pt/C (E1/2 = 0.89 V in alkaline and E1/2 = 0.84 V in acidic media). Furthermore, a high power density and a long‐term operation within 6 h of direct methanol fuel cell based on brilliant Fe‐N‐C‐2 verify a great promising application of potable power devices in the future.
