Abstract
DSC is a thermoanalytical technique in which the difference in the amountofheat required to increase the temperature of a sample and reference are measured as a function of temperature. Differential scanning calorimetry can be used to measure a number of characteristic properties of a sample.
Glass transitions may occur as the temperature of an amorphous solid is increased. Th
features1.
fuel cell is a kind of generator that provides electricity, batteries are like warehouses that store electricity.
features2.
The maximum output energy from the battery
= 50% forms of energy+50% heat
=>The energy efficiency is 50%.
features3.

Amountof organic waste is approximately 8,300tons/year by 2008 and 2007, among which only about 7% (6.1million tons/year) are used to source of energy (biogas).
Bio-gas produced by using organic waste were used mostly as a heating fuel
