... activity for iodide/triiodide redox reaction. This paper presents a systematic comparative study on exploring and understanding the performance of DSSC using cobalt sulphate as a counter electrode material in place of platinum or graphite. However, platinum being costly, other materials like graphite...

... energy storage density at a constant temperature corresponding to its phase transition temperature. In this paper, a high temperature PCM (melting temperature of 80 ° C ) made of a composite of paraffin and graphite was tested to determine its thermal properties. Tests were conducted with a differential...

.... The most significant one is the lower reduction temperatures ( 850 – 900 ° C for the SnO 2 versus 1100 – 1150 ° C for the ZnO). The rate of carbothermal reduction was studied experimentally. SnO 2 powder (300 mesh, 99.9% purity) was reduced with beech charcoal and graphite using a thermogravimetric...

...S. Pincemin; X. Py; R. Olives; M. Christ; O. Oettinger New thermal storage composites made of graphite and PCM ( Na N O 3 ∕ K N O 3 eutectic) have been developed for solar thermal power plants using direct solar steam generation. Those materials, obtained using different elaboration routes...

... to a closed multireheat Brayton power cycle using nitrogen or helium as the working fluid. During the daytime, hot salt may also be used to heat graphite, which would then be used as a heat storage medium to make night-time operations possible. Graphite is a low-cost high-heat-capacity solid...

... storage tanks, thus reducing cost and space. The present work uses a paraffin-graphite composite as the PCM to increase the conductivity of the PCM matrix. The paraffin’s melting point is around 89 ° C , which is appropriate for use in single-effect absorption systems. The mathematical model...
