The rapid growth of intermittent renewable energy (e.g., wind and solar) demands low-cost large-scale storage systems for smooth reliable power output, where redox-flow batteries (RFBs) could find their niche. In this work, we introduce the first all-soluble all-iron RFB based on iron as same redox-active element but with different coordination chemistries in alkaline aqueous system. adoption largely alleviates challenging problem cross-contamination metal ions RFBs that use two elements. An...
Low-temperature direct ammonia fuel cells (DAFCs) can use carbon-neutral as a fuel, which has attracted increasing attention recently due to ammonia's low source-to-tank energy cost, easy transport and storage, wide availability.
Here, we have developed a dissolved oxygen and galvanic corrosion method to synthesize vertically aligned fluoride-incorporated nickel–iron oxyhydroxide nanosheet arrays on compressed Ni foam as an efficient self-supported evolution electrode. It is integrated with poly(aryl piperidinium) hydroxide exchange membrane ionomers high ion capacity into electrolyzer fed pure water, which achieves performance of 1020 mA cm–2 at 1.8 V prevents the detachment catalysts during continuous operation...
Hydroxide exchange membrane fuel cells (HEMFC) are a promising power source for automobiles due to their low cost. Here we focus on improving the beginning-of-life performance of HEMFCs higher level with poly(aryl piperidinium) (PAP) membranes and ionomers. We find that lower RH backpressure in anode than cathode can eliminate flooding dryout so balanced water management be achieved. also PtRu/C is better catalyst Pt/Ketjen Black presence Ru Pt/Vulcan XC-72 its mass transport properties....
A new anion conducting covalent organic framework (COF) was prepared by covalently tethering quaternary ammonium (QA) ions onto the pore walls of COF 1,3,5-triformylphloroglucinol-<italic>o</italic>-tolidine (TpBD-Me) through bromination and quaternization.
Recently, ammonia has become more attractive for carbon-neutral transportation. Both aqueous and gaseous can be utilized direct hydroxide exchange membrane fuel cells (DAFCs). Using as feedstock DAFCs presents significant drawbacks to practical stack operations, including higher crossover rate, increased probability of cathode flooding, shunt currents. These make the ideal DAFCs. However, main obstacle adopting gas-fed is their poor performance. Here, we demonstrate that anode humidity...
The low-temperature direct ammonia fuel cell (DAFC) is an attractive option for zero-emission transportation. However, the demonstration of high-performance and durable DAFCs identification their suitable market are not yet reported. Here, we show a DAFC enabled by hydrophobic spinel cathode, which achieves peak power density 410 mW cm−2 continuous operation 80 h at 300 mA cm−2. We assemble five 50 cm2 cells into 75 W stack, showing comparable area-specific performance to that single cell....
Hydroxide exchange membrane (HEM) water electrolysis is promising for green hydrogen production due to its low cost and excellent performance. However, HEM often has insufficient stability in strong alkaline solutions, particularly under in-situ operation conditions, hindering commercialization. In this study, we discover that the of primarily impaired by locally accumulated heat thermal conductivity. Accordingly, propose highly thermally conductive HEMs with an efficient three-dimensional...
Abstract Designing highly stable anion exchange membranes (AEMs) is of vital importance for membrane fuel cells (AEMFCs). Herein, the study presents that elevating current density and reducing relative humidity can dramatically lower local hydration number (λ) cathode in AEMFCs therefore result rapid degradation AEMs. To address this issue, a water‐retention strategy has been proposed to alleviate hydroxide attack. The crosslinked poly (aryl N‐silanylmethyl‐piperidinium) (Si‐TP‐100‐x) AEMs...
The motivations to operate the direct ammonia fuel cell (DAFC) with no addition of aqueous base, include facilitated management and prevention corrosion shunt currents in DAFC stack. We describe here a polymer electrolyte DAFC, operating at temperature (T ) 120 °C on water alone as anode feed, that demonstrated peak power 180 mW cm −2 —a record for this type cell. offer detailed analysis polarization curves recorded PE-DAFCs T range 60 °C–120 °C, allowing estimate effects KOH-free operation...
Microcapsules have been widely used in drug carriers, nano/microreactors, artificial organelles for their empty space and functional shell. synthesized from spherical liquid-liquid interface show ultrathin shell large cavities. However, interfaces generated by stirring or sonicating are difficult controlling the droplet size preventing coalescence, which results inhomogeneous capsules. Here, we demonstrate a microfluidic interfacial synthetic method to produce microcapsules using hot...
