Fuel cells with an operational range of-20 °C to 200 °C enabled by phosphoric acid-doped intrinsically ultramicroporous membranes

Hongying Tang et al.

Summary: Researchers have developed a new type of fuel cell membrane that can operate over a wider temperature range, from -20 to 200 degrees C. This ultramicroporous membrane retains phosphoric acid even under highly humidified conditions and exhibits higher proton conductivity retention compared to conventional membranes. This innovation could simplify heat and water management in fuel cell systems, potentially reducing costs.

Semi-Solid Superprotonic Supramolecular Polymer Electrolytes Based on Deep Eutectic Solvents and Polyoxometalates

Haikun Guo et al.

Summary: Semi-solid bulk supramolecular polymer (SP) materials were fabricated by using polyoxometalate (POM) nanoclusters as supramolecular cross-linkers to solidify a deep eutectic solvent (DES). The resulting materials exhibited high proton conductivity and mechanical strength, and formed a stable electrode-electrolyte interface by a melt-infiltration strategy, leading to improved performance in supercapacitors.

Nanostructured high-performance electrolyte membranes based on polymer network post-assembly for high-temperature supercapacitors

Minghao Zeng et al.

Summary: This study reports on the fabrication of high-performance proton conductive PEMs for high-temperature supercapacitors using a post-assembly strategy, achieving high stability and high conductivity. By controllable cross-linking and inducement of phosphoric acid, bicontinuous nanostructure PEMs with excellent performance at high temperatures (150°C) were prepared. The HT-SCs based on these PEMs exhibited specific capacitance of 138.0 F g(-1) and high capacitance retention of 80.0% after 2500 galvanostatic charge-discharge cycles, showing outstanding high-temperature capacitance and cycle stability.
