The state-of-the-art of polymer electrolyte membrane fuel cell (PEMFC) technology is based on perfluorosulfonic acid (PFSA) membranes operating at a typical temperature 80 °C. Some the key issues and shortcomings PFSA-based PEMFC are briefly discussed. These include water management, CO poisoning, hydrogen, reformate methanol as fuels, cooling, heat recovery. As means to solve these shortcomings, high-temperature for operation above 100 °C under active development. This treatise devoted...
Nonprecious metal catalysts for the oxygen reduction reaction are ultimate materials and foremost subject low-temperature fuel cells. A novel type of prepared by high-pressure pyrolysis is reported. The catalyst featured hollow spherical morphologies consisting uniform iron carbide (Fe3 C) nanoparticles encased graphitic layers, with little surface nitrogen or metallic functionalities. In acidic media outer layers stabilize without depriving them their catalytic activity towards (ORR). As a...
Abstract Proton exchange membrane fuel cell (PEMFC) technology based on perfluorosulfonic acid (PFSA) polymer membranes is briefly reviewed. The newest development in alternative electrolytes for operation above 100 °C summarized and discussed. As one of the successful approaches to high operational temperatures, evaluation doped polybenzimidazole (PBI) are reviewed, covering synthesis, casting, doping, physicochemical characterization testing. A temperature PEMFC system, at up 200...
The CO poisoning effect on carbon-supported platinum catalysts (at a loading of 0.5 mg per electrode) in polymer electrolyte membrane fuel cells (PEMFCs) has been investigated temperature range from 125 to 200°C with the phosphoric acid-doped polybenzimidazole membranes as electrolyte. is very temperature-dependent and can be sufficiently suppressed at elevated temperature. By defining tolerance voltage loss less than 10 mV, it evaluated that 3% hydrogen tolerated current densities up 200°C,...
Abstract Iron single atom catalysts (Fe SACs) are the best‐known nonprecious metal (NPM) for oxygen reduction reaction (ORR) of polymer electrolyte membrane fuel cells (PEMFCs), but their practical application has been constrained by low Fe SACs loading (<2 wt%). Here, a one‐pot pyrolysis method is reported synthesis iron atoms on graphene (FeSA‐G) with high SAC ≈7.7 ± 1.3 wt%. The as‐synthesized FeSA‐G shows an onset potential 0.950 V and half‐wave 0.804 in acid ORR, similar to that Pt/C...
New and emerging technologies for electrochemical energy conversion processes challenging separations have been major drivers the tremendous development of new polybenzimidazole chemistries materials in recent years.
Abstract In this work, the atmospheric corrosion of carbon steels was monitored at six different sites (and hence, conditions) using Fe/Cu-type monitoring technology over a period 12 months. After analyzing 3 million data points, sensor were interpretable as instantaneous rate, and “corrosivity” for each exposure environment showed highly dynamic changes from C1 to CX level (according ISO 9223 standard). A random forest model developed predict rate investigate impacts ten “corrosive factors”...
Revolutionary developments in analytical chemistry have led to the rapid development of self-powered photoelectrochemical (PEC) sensors. Different from conventional PEC sensors, sensors do not require an external power source or complex devices for sensitive detection targets. As a result, these enormous application potential novel portable An increasing body work is making excellent progress toward implementation detection, but there been no reviews date. The present review first introduces...
Polybenzimidazole membranes have been covalently cross-linked after casting. The exhibit much-improved chemical stability and mechanical strength. This allows the membrane to be doped at higher acid levels therefore possess proton conductivity potentially increased durability in fuel cells.
Polybenzimidazole (PBI) and polysulfone (PSF) compose an immiscible polymer pair; the introduction however of functional groups such as sulfonate in polymeric chain PSF resulted formation miscible blends with PBI. The miscibility behavior a series PBI sulfonated (SPSF) at various sulfonation levels has been studied by dynamic mechanical analysis (DMA), FT-IR, FT-Raman spectroscopy. DMA shown that degree well blend composition controls system. In respect, partially or were obtained when level...
Abstract Hexafluoropropylidene polybenzimidazole (F 6 PBI) was synthesized with excellent chemical stability and improved solubility. When doped phosphoric acid, however, the F PBI membranes showed plastic deformation at elevated temperatures. Further efforts were made to covalently crosslink chloromethyl polysulfone as a polymeric crosslinker. Comparing linear m membranes, polymer crosslinked exhibited little organo solubility, towards radical oxidation, high resistance swelling in...
