First Time

A new solid high-proton conductor Na7[CoW11O39Cd (H2O)]·12H2O has been synthesized for the first time. The percentage composition of the product were determined by Inductively coupled plasma (ICP) and X-ray photoelectron spectroscopy (XPS). The product was characterized by infrared spectroscopy (IR) and X-ray diffraction (XRD), which indicate it possesses the Keggin structure. The TG-DTA curve shows the sequence of water loss in the compound, the amount of the loss, as well as the thermostability. Conductivity of the compound was investigated by four-electrode method at room temperature and different measuring temperatures, the results reveal that its proton conductivity is 4.87×10−4S·cm-1at 27oC and the activation energy for proton conduction is 15.31 kJ/mol.

Fuel Cell Operation

Protogenic phytic acid is immobilized by its gelation with iron nitrate in DMF. The resulting pelletized xerogel is observed to show a high proton conductivity of 2.4 × 10−2 S cm−1 at 120 °C and is tried as solid electrolyte for dry H2/O2 fuel cell operation.
