摘要： Gel polymer electrolytes comprising molybdate(VI) salts dispersed in a hydrogel matrix. The hydrogel matrix contains reacted units of an acrylamide (e.g. 2-acrylamido-2-methyl-1-propanesulfonic acid) and optionally an additional monomer. A supercapacitor including the gel polymer electrolyte and electrodes arranged between the electrolyte is also specified. This supercapacitor is evaluated on its specific capacitance, energy density, power density, resistance, as well as cycling stability.

摘要： A bio-electrochemical fuel cell is provided. The fuel cell includes an anode placed between a second endplate and a supporting plate, a cathode placed between a first endplate and the supporting plate, a separator plate provided between the first endplate and the cathode, a separator plate provided between the second endplate and the anode, and at least one separator plate provided on each side of the supporting plate. The anode has a first layer and a biofilm including photosynthetic microorganisms is present on a surface of the first layer. A central aperture of the first endplate receives a flow of water containing the photosynthetic microorganisms and a central aperture of the second endplate discharges the flow of water. Application of light to the fuel cell assembly causes the photosynthetic microorganisms to release oxygen at the anode and induces a photo-current in the anode.

摘要： A poly(vinylphosphonic acid) (PVPA) - (NH4)2MoO4), gel polymer electrolyte can be prepared by incorporating redox-mediated Mo, or similar metal, into a PVPA, or similar polymer, matrix. Gel polymer electrolytes including PVPA/MoX, x representing the percent fraction Mo in PVPA, can be used to make supercapacitors including active carbon electrodes. The electrolytes can be in gel form, bendable and stretchable in a device. Devices including this gel electrolyte can have a specific capacitance (Cs) of 1276 F/g, i.e., a more than 50-fold increase relative to a PVPA system without Mo. A PVPA / Mo10 supercapacitor can have an energy density of 180.2 Wh/kg at power density of 500 W/kg, and devices with this hydrogel structure may maintain 85+% of their initial capacitance performance after 2300 charge-discharge cycles.
