“…The membranes showed good mechanical properties, methanol barrier, stability, and conductivity, demonstrating their suitability as PEMs in DMFC. 14 In recent years, a large amount of agricultural waste stalk has been discarded or incinerated in situ, which not only destroys the soil structure and reduces the quality of farmland but also pollutes the environment. Stalk with a large amount of carbon elements is a promising source of carbon-based functional materials.…”

The cross-linked sulfonated sodium alginate/modified carbon quantum dot (SSA/MCQD) polyelectrolyte membranes were prepared with sulfonated sodium alginate biomass as a substrate and modified carbon quantum dot from agricultural waste corn stalk as additive. The performance of polyelectrolyte membranes with various MCQD contents were investigated in detail. The results showed that compared with the SSA membrane without MCQD, the SSA/MCQD membranes showed better thermodynamic, dimensional, hydrolytic, and oxidative stability. In addition, the introduction of MCQD enhanced the mechanical strength, proton conductivity, methanol barrier, and cell performance of polyelectrolyte membranes. The membrane with 2.0 wt % MCQD (SSA/MCQD-2.0) exhibited the best adaptability as a proton exchange membrane for direct methanol fuel cell (DMFC) application. Compared with SSA membrane, the 10% weight loss temperature and tensile strength of SSA/MCQD-2.0 were increased by 20 °C and 42.9%, respectively, the methanol diffusion coefficient (3.82 × 10 −7 cm 2 s −1 ) was reduced by 51%, the selectivity (1.34 × 10 6 Ss cm −3 ) was expanded by 3 times, and the maximum power density was increased by 42.7%. Hence, the cross-linked SSA/MCQD polyelectrolyte membranes, especially SSA/ MCQD-2.0, had great potential for DMFC application because of the high performance, cheapness, and environmental friendliness.

“…Nafion PEMs have high proton conductivity owing to the well-connected ionic pathways formed by their unique perfluorinated chemical structure . Actually, the existence of anisotropy between the in-plane and through-plane proton conductivity has been reported in Nafion membranes. − The in-plane proton conductivity of Nafion PEMs was measured to be in the range of 80–120 mS·cm –1 with a four-probe electrode − and the through-plane proton conductivity of Nafion PEMs was determined to be in the range of 20–50 mS·cm –1 by a two-probe electrode. − ,− The measurement results of the proton conductivity of Nafion PEMs by the four-probe electrode method are usually higher than those by the two-probe electrodes. − It has been reported that the PEM with high through-plane proton conductivity is profitable in preparing high-performance fuel cells. − However, Nafion PEMs still suffer from certain limitations including a complex synthetic process, high production cost, and high fuel permeability. , Nonperfluorinated hydrocarbon-based materials with rigid polymer chains, such as sulfonated poly(aryl ether ketone), , sulfonated poly(ether ether ketone), sulfonated poly(arylene ether sulfone), − sulfonated polybenzimidazole, sulfonated polystyrene, − etc., have been reported to be potentially applied to proton exchange membranes.

Sulfonated polystyrene-b-polyisobutylene-b-polystyrene copolymers (SSIBS) with various average molar percentages of sulfonic acid side groups based on all the structural units along SSIBS polymer chains (SP) were synthesized via sulfonation of SIBS with acetyl sulfate. A transmission electron microscopy (TEM) method was developed to directly observe the dark phase of −(SO 3 ) 2 Pb ionic channels of sulfonic acid ion clusters by the ion exchange of H + with Pb 2+ . The size of hydrophilic ionic channels in SSIBS enlarged with increasing SP and the desired interconnected ionic transport channels could be formed in SSIBS with SP of more than 6.9 mol %. Effects of copolymer composition and functionality on micromorphology and finally on electrochemical properties of the SSIBS membranes show that the SSIBS membranes with bicontinuous phase separation micromorphology exhibit high throughplane proton conductivity, low fuel permeability, and high selectivity. The optimized SSIBS-3160−13.4 membrane was selected for assembling the single direct methanol fuel cell (DMFC) and the DMFC exhibits high performances of open circuit voltage (OCV) of 560 mV, limiting current density (J lim ) of 650 mA•cm −2 , and peak power density (P max ) of 32.24 mW•cm −2 . These fuel cell performances are similar to those (OCV = 510 mV, J lim = 600 mA•cm −2 , and P max = 35.56 mW•cm −2 ) by using the commercial Nafion 117 membrane under the same conditions. To the best of our knowledge, this is the first example of SSIBS-based DMFC exhibiting comparable performances with Nafion 117 under the same test conditions.

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.
