“…4 Regardless of the advantages of DMFCs, there are some restrictions in the development and progress of DMFCs, including low performance of the MOR, utilization of expensive noble metals as catalysts and the sensitivity of the catalysts for poisoning by the resulting CO generation during the MOR. [5][6][7] It is known that catalysts play a crucial role in DMFCs for their future applications. In this regard, Pt is widely considered as the most efficient electrocatalyst for the MOR considering the efficient role played by Pt in the MOR.…”

“…To complete the reaction, electrons and protons move to the cathode side through an external electric circuit and proton transport membrane. The oxygen reduction reaction (ORR) occurs in the cathode electrocatalyst by reacting protons, electrons, and oxygen, where water molecules exist as a byproduct [ 53 , 54 , 55 , 56 ]. DMFCs release greenhouse gas emissions (CO 2 ) during unit cell operation.…”

A direct methanol fuel cell (DMFC) is an excellent energy device in which direct conversion of methanol to energy occurs, resulting in a high energy conversion rate. For DMFCs, fluoropolymer copolymers are considered excellent proton-exchange membranes (PEMs). However, the high cost and high methanol permeability of commercial membranes are major obstacles to overcome in achieving higher performance in DMFCs. Novel developments have focused on various reliable materials to decrease costs and enhance DMFC performance. From this perspective, cellulose-based materials have been effectively considered as polymers and additives with multiple concepts to develop PEMs for DMFCs. In this review, we have extensively discussed the advances and utilization of cost-effective cellulose materials (microcrystalline cellulose, nanocrystalline cellulose, cellulose whiskers, cellulose nanofibers, and cellulose acetate) as PEMs for DMFCs. By adding cellulose or cellulose derivatives alone or into the PEM matrix, the performance of DMFCs is attained progressively. To understand the impact of different structures and compositions of cellulose-containing PEMs, they have been classified as functionalized cellulose, grafted cellulose, acid-doped cellulose, cellulose blended with different polymers, and composites with inorganic additives.

“…Several efficient and engineered catalysts have been introduced; however, none of them can compete with catalysts such as platinum, palladium, and ruthenium. Alcohol fuel cells based on these catalysts are expensive and have a gradual loss of electrocatalytic activity in alcohol oxidation [ 14 ].…”

Recently, transition metal oxides have been considered for various applications due to their unique properties. We present the synthesis of a three-component catalyst consisting of zirconium oxide (ZrO2), nickel oxide (NiO), and reduced graphene oxide (rGO) in the form of ZrO2/NiO/rGO by a simple one-step hydrothermal method. X-ray powder diffraction (XRD), scanning electron microscope (SEM), and bright-field transmission electron microscopy (BF-TEM) analyses were performed to accurately characterize the catalysts. Cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and linear sweep voltammetry (LSV) analyses were also carried out to investigate the methanol and ethanol alcohol electrooxidation ability of the synthesized nanocatalysts. Inspired by the good potential of metal oxides in the field of catalysts, especially in fuel-cell anodes, we investigated the capability of this catalyst in the methanol oxidation reaction (MOR) and ethanol oxidation reaction (EOR). After proving the successful synthesis and examining the surface morphology of these materials, detailed electrochemical tests were performed to show the outstanding capability of this new nanocatalyst for use in the anode of alcohol fuel cells. ZrO2/NiO/rGO indicated a current density of 26.6 mA/cm2 at a peak potential of 0.52 V and 99.5% cyclic stability in the MOR and a current density of 17.3 mA/cm2 at a peak potential of 0.52 V and 98.5% cyclic stability in the EOR (at optimal concentration/scan rate 20 mV/s), representing an attractive option for use in the anode of alcoholic fuel cells.
