“…The PEMFC membrane, with its high cost 155 , poor durability 29 and intolerance to fuel impurities 156 , represents another obstacle to the widespread commercialization of transport PEMFCs. The current commercial baseline, Nafion®, is a perfluorinated membrane that 14 performs poorly in temperatures beyond 80 °C and in low-humidity environments, and is not stable with impure feed gases 157,158 .…”

Electric vehicles (EVs) powered by lithium ion batteries (LIBs) or proton exchange membrane hydrogen fuel cells (PEMFCs) offer important potential climate change mitigation effects when combined with clean energy sources. The development of novel nanomaterials may bring about the next wave of technical improvements for LIBs and PEMFCs. If the next generation of EVs is to lead to not only reduced emissions during use but also environmentally sustainable production chains, the research on nanomaterials for LIBs and PEMFCs should be guided by a lifecycle perspective. In this Review, we describe an environmental lifecycle screening framework tailored to assess nanomaterials for electromobility. By applying this framework, we offer an early evaluation of the most promising nanomaterials for LIBs and PEMFCs and their potential contributions to the environmental sustainability of EV lifecycles. Potential environmental trade-offs and gaps in nanomaterials research are identified to provide guidance for future nanomaterial developments for electromobility.

“…These PEMs such as Nafion are currently the most commercially membranes for MFCs, with chemical stability, conductivity and mechanical properties. While PEMs have satisfactory properties for fuel cells, they limit commercial use due to high costs (13). To improve electricity production and columbic efficiency (CE), the development of low-cost materials is essential for scaling up MFCs and creating low-cost treatment systems.…”

One limiting aspect to make microbial fuel cells (MFCs) a viable technology is to obtain low cost and environmentally sound materials for their components. In this work we synthesized membranes by a simple procedure involving low price and biodegradable materials such as poly (vinyl alcohol) (PVA), chitosan (CS) and PVA:CS, all cross-linked with sulfuric acid; they were compared to Nafion®, as our reference/control membrane. PVA:CS show lower oxygen permeability in comparison to Nafion® membranes, a strong advantage in order to maintain anaerobic conditions in the anodic compartment of MFCs. Membranes were characterized in typical H-Type MFCs, and results show that PVA:CS membranes outperform Nafion® 4 times (power production) while being 75 times more economic. Moreover, we design a paper-based micro-scale MFC, which was assayed as a toxicity biosensor; we obtained results in less than 20 min using 16 μL volume samples containing formaldehyde as a model toxicant. The PVA:CS membrane presented here can offer low environmental impact (materials, fabrication and disposal) and become a very interesting option for point of need single use disposable analytical devices.
